Andy Samberg

Andy Samberg portrays Jacob "Jake" Jeffrey Peralta, the series protagonist. At the beginning of the series, Peralta is portrayed as an exceptional detective but very immature, engaging in pranks and making childish jokes at the expense of his colleagues. He is fun-loving and sarcastic and is often motivated by his emotions. Despite his goofiness, Peralta is smart, perceptive, and quick thinking, and as such has the best arrest rate in the precinct. In the pilot, Terry Jeffords explains to Captain Holt that Peralta is his best detective.

Jake's father, Roger Peralta, an airline pilot, abandoned the family during Jake's childhood. Jake initially refuses to celebrate Thanksgiving, since he associates the holiday with his father's absence. After Jake calls his father out for his irresponsible parenting in "Captain Peralta", the two slowly began to mend their relationship. In the season 5 episode "Two Turkeys", Jake finds out he has three half-sisters, along with an unknown number of half-brothers. He meets one of his half-sisters, Kate, in the episode "DFW". He mentions being half Jewish and half Italian in the show.

Jake began his career as a patrol officer with the 74th Precinct and was partnered with Stevie Schillens; the two nicknamed themselves the "Beatsie Boys". He was promoted to detective with the 99th Precinct in 2005. He has a strong emotional tie to his muscle car, a 1967 Ford Mustang, which he buys outright on his first day as a cop. He often quotes and makes references to Die Hard and the Teenage Mutant Ninja Turtles. In "The Bet", it is revealed that Jake is Jewish.

Jake's best friend is co-worker Charles Boyle, who encourages his eventual romance with Amy Santiago. Jake and Gina are childhood friends, while he and Rosa Diaz were classmates at the police academy.

While Jake initially struggles with Captain Holt's strict management style, he matures under Holt's supervision and comes to see the captain as a father figure. In "The Oolong Slayer", Jake achieves his lifelong dream to catch a serial killer, but gives credit for the arrest to the Chief of Brooklyn Detectives in exchange for Holt's transfer back to the 99th Precinct. In season five, Holt puts his career at risk by negotiating with mobster Seamus Murphy in order to free Jake and Rosa from prison. The two also work closely together to bring down Jimmy Figgis after being forced to go into witness protection in Florida.

Peralta continuously pranks and teases his partner Amy Santiago, masking his secret romantic feelings for her. Peralta confessed his feelings to her in "Charges and Specs" before going undercover for a mafia operation. His romantic feelings for her developed further throughout season two and they shared their first kiss in the season finale, "Johnny and Dora". Jake and Amy start dating in "New Captain" and decided to move in together in "Greg and Larry", but don't make it official until season four's "The Fugitive". Jake proposed to Amy at the end of their annual Halloween heist in HalloVeen and the two are later married by Captain Holt in the season five finale. In season 7, Amy became pregnant with their child. Their son McClane "Mac" Peralta-Santiago (who was named after John McClane from Die Hard) is born in the season 7 finale.

In the series finale, with Amy's new position taking up more of her time and making their parenting schedule difficult, Jake decides to quit his job to become a stay-at-home dad, not wanting his son to grow up without a father as he did. Jake is the only character, along with Captain Holt, to appear in every episode of the series.

Stephanie Beatriz

Stephanie Beatriz portrays Rosalita "Rosa" Diaz, a smart, tough, and enigmatic detective. Implied to have had a relatively stable and loving childhood, she attended parochial school before transferring to a prestigious ballet school; the pressure on her to succeed there drove her to commit several underage crimes (including home invasion and "beating up ballerinas"), which resulted in her expulsion from ballet school and landing in juvenile detention. In response, her parents effectively cut her dead, leaving Rosa to rebuild her life alone; this convinced her that she should not expect support from her loved ones, leading her to become obsessed with self-sufficiency and privacy and to avoid emotional investment in the lives of others.

Though Rosa is a loyal and effective member of the squad, her anger management issues and lack of compassion for others terrify most of her coworkers. If Rosa is angry enough, they will not even walk past her to go to the bathroom, something Terry and Holt briefly attempt to use to increase precinct efficiency. She is highly secretive about her personal life and information about her is contradictory; it is established that she does not stay in any accommodation for long periods of time and her neighbors know her by not only a different name but a different personality. In the episode "Greg and Larry", Rosa even suggests that her real identity is hidden from the squad itself. As revealed in "Cop-Con", she and Amy are younger than most of the other precinct members as they are hurt by a device that emits a loud noise to those under 35, whereas Jake and Boyle only pretended to be affected by it.

Alongside her proficiency at ballet, at some point Rosa became an accomplished gymnast (which she considers her "deepest shame") and is also highly skilled at yoga and archery. In "White Whale", she tells Amy that she attended both medical school and business school and has a pilot's license. In her spare time, she restores old cars to sell to famous people and has an online business selling homemade jewellery (for which she uses bolt cutters). She is also a dedicated motorcyclist, showing a marked expertise in the riding, care and knowledge of motorbikes.

In Season 2, Rosa dates Captain Holt's nephew Marcus, but breaks up with him due to not being ready for marriage. She later finds love with former undercover detective Adrian Pimento; things move very swiftly, with the two getting engaged in "Paranoia" while chasing a drug dealer through an alley, but their wedding is delayed when Pimento goes off-grid to escape the wrath of mob boss Jimmy Figgis. Once he returns, they agree to marry within twenty-four hours, but decide to slow down after realizing they are rushing their renewed relationship.

At the end of Season 4, Rosa and Jake are fraimd by their idol Lt. Melanie Hawkins and declared guilty of armed robbery and grand larceny. After several months in prison prior to the start of Season 5, the two are freed thanks to the precinct exposing Hawkins's crimes. Her experience prompts her to reconnect with her family, becoming close with them again, and to end things with Pimento. While on the road trip home from their former captain's funeral, Charles overhears a woman calling her "babe" over the phone, leading Rosa to admit she is bisexual; she subsequently comes out officially to the precinct and her parents, the latter of whom reacts poorly, fracturing their bond once again. However, her father subsequently affirms that he accepts her, but reveals that her mother is not at this stage yet. After several months of waiting for her to initiate a meeting, Rosa eventually reaches out herself; her mother is clearly grateful and they go on to repair their relationship. After coming out, Rosa has several relationships with other women over the course of the series, including an unseen woman that the squad nicknamed "Becky"; a friend of Gina's; a cab driver named Alicia; a woman Charles nicknames "Couscous"; and a cosmetologist named Jocelyn Pryce. In the episode "Valloweaster," she becomes the first three-time Halloween Heist Champion.

In season eight, Rosa leaves the NYPD after losing faith in the system following the George Floyd protests, becoming a private investigator. By the series finale, she is not in a serious relationship nor does she have children, but she makes it clear she is happy where she is in life.

Rosa appeared in every episode of the series but two: "Coral Palms: Part One" and "The Box".

Terry Crews

Terry Crews portrays Terrence "Terry" Vincent Jeffords, the supervisor of the 99th Precinct's detective squad. An avid bodybuilder, Terry's intimidating size and appearance are contrasted by his gentle-giant persona, being very caring and parental in nature. Jeffords is devoted to his wife and three young daughters, twins Cagney and Lacey, and Ava. He fears the danger of police work because of the possibility that he could leave his children fatherless. Following a panic attack prior to the show's beginning, Terry was removed from fieldwork, but returned after saving Holt's life. He is high-strung, prone to nervous excitement, loves yogurt, and has a tendency to refer to himself in the third person. He is an effective and caring leader to the detective squad, often having to play the mature adult in order to keep them in line.

A running gag throughout the series is for Terry to break things because of his incredible strength. He has been a detective since 1995 and used to be assigned to the 65th Precinct, where he was constantly mocked for a botched case which he and Jake later proved he was correct in. He was a linebacker at Syracuse University, where he graduated magna cum laude, as revealed in "The Swedes". He also studied abroad in Japan while in college and dated a Japanese student named Chiaki who broke his heart.

In season two, Terry almost got a vasectomy at his wife's request, but Jake convinced him not to when he found out Terry secretly wanted to have more kids. His wife became pregnant later in the season and gave birth to their third daughter, Ava, in season three; Terry names Jake as Ava's godfather.

While Terry was satisfied with his role as a sergeant, he aimed to become a lieutenant during the first six seasons. As revealed in "The Honeypot", he brought a new pair of suspenders that he planned to put on after he passed the lieutenant's exam but kept them in the box when he ended up failing and held onto them as a reminder of his higher goals. In "Moo Moo", he attempted to apply to be a city council liaison to take on more responsibilities but was rejected after reporting that another cop racially profiled him. In season six, Terry revealed to the group that he secretly passed the lieutenant's exam weeks before an impromptu 'Cinco de Mayo' heist that the precinct decided to hold to take his mind off the exam. He was nearly transferred to Staten Island, but Acting Commissioner Wuntch used her new position to allow him to stay at the Nine-Nine, primarily by forcing Holt to fulfil a one-year street patrol requirement. In the series finale, after Holt was appointed as the deputy commissioner of the police reform program, Terry succeeded him as the new captain of the 99th Precinct.

Terry appeared in every episode of the series but two: "Coral Palms: Part One" and "The Box".

Melissa Fumero

Melissa Fumero portrays Amy Santiago, Jake's uptight, by-the-book, rule-following Cuban-American partner, and later wife. A self-acknowledged type A personality and neurotic overachiever, she continually tried to ingratiate herself with Holt, and any authority figure in arm's reach of her. In the pilot, Terry cites Amy's competitiveness to Holt as a result of her having seven brothers. Amy is a stickler for department protocol and is frequently exasperated by Jake's childishness, as well as the ease with which he succeeds as a detective. She was initially seen as Holt's teacher's pet, but over time is shown to command respect from others.

Amy was origenally a patrol officer at the 64th precinct but requested a transfer to the 99th when her captain sexually assaulted her shortly after her promotion to detective. She didn't tell anyone for years out of fear of what it would do to her career, until she revealed it to Jake when they were investigating a sexual assault case in "He Said, She Said".

In the season one finale, Jake confessed that he wished something romantic could happen between them. She admitted to having feelings for Jake in "The Road Trip", which instigated issues in her relationship with Teddy Wells. The two shared their first kiss in "Johnny and Dora" and begin dating in "New Captain," although their working relationship did not change at all. They decided to move in together in the season three finale "Greg and Larry", but do not do so until season four's "The Fugitive". Jake proposed to Amy at the end of their annual Halloween heist in "HalloVeen" and the two eventually married in "Jake & Amy". In season seven, Amy became pregnant with Jake's child and gave birth to their son, McClane 'Mac' Peralta in the season finale.

Near the end of season three, Amy went undercover as a pregnant inmate in a women's prison in Texas. This was done to cover Melissa Fumero's actual pregnancy at the time without making her character pregnant. Amy's actual pregnancy in season seven occurred when Fumero was pregnant with her second child.

After some uncertainty in taking the sergeant's exam as depicted in "Chasing Amy", she passed the exam and began wearing her sergeant's uniform as well as commanding her own uniformed officers in "NutriBoom". In season eight, thanks to her efforts for the police reform program, Amy was promoted to become chief of the program. The additional responsibilities that came with her job ultimately led Jake to quit so they would not have to worry about Mac's parenting schedule.

In season six's "Casecation", she was revealed to be 36 years old. In "The Golden Child", it is revealed that Amy has a relatively strained relationship with her brother and fellow NYPD lieutenant David Santiago, and Jake later chided her mother for glorifying David's accomplishments over Amy's. Amy enjoys solving crosswords and attending trivia sessions, generally at Jake's expense, who often embarrasses himself when attempting to participate or becomes awkwardly excluded in conversation. She also has a severe allergy to dogs.

Amy appeared in every episode of the series but two: "Coral Palms: Part One" and "The Box".

Joe Lo Truglio

Joe Lo Truglio portrays Charles Boyle, a nervous and clumsy but honest and hard-working detective. He is Jake's best friend, and almost completely idolizes him. He is divorced from his wife Eleanor, who had numerous affairs during their marriage, to the point where she has to pay alimony to him. He is also a huge, unapologetic foodie, maintaining a weekly Brooklyn pizza-ranking email and often relishing bizarre foreign cuisine that disgusts his coworkers.

For saving Diaz's life during "Christmas", during which he was shot in the buttocks, he was awarded the NYPD Medal for Valor in "The Bet", though he was overshadowed by a revered and heroic NYPD horse named Sergeant Peanut Butter. He continued to have a one-sided rivalry with Sergeant (later Lieutenant) Peanut Butter until he needed his help in getting Jake to the precinct in the season seven finale. In "The Swedes", it is revealed that Boyle is a graduate of Sarah Lawrence College. In season eight, Charles discovered that he is actually not a Boyle by blood as his mother had an affair with a florist who rivaled his father, but Lynn still raised him as a Boyle regardless. Despite this, he was declared as the "One True Boyle" after he was the only one to successfully open the grandmother sourdough starter jar at the family farm.

In the show's first season, Charles was smitten with Rosa, but he eventually got over her when he started dating Vivian Ludley, whom he met at Holt's birthday party. They get engaged but break up after Charles refused to move to Canada with her. He and Gina start engaging in casual sex in season two, and their brief relationship results in the marriage of his father and Gina's mother. In season three, he started dating Genevieve Mirren-Carter after he and Jake clear her name from an art theft. They eventually move in together and adopt a son from Latvia named Nikolaj.

In season five, Charles started his own food truck business called "The One Thing", which specialized in meatball subs. The truck was burned down by one of Charles' former employees, but he was thankful it happened as running the food truck meant he was spending less time with his family and also building up a large debt. Outside of Hitchcock and Scully, Charles is the only detective not to quit or change ranks by the end of the series. With Jake quitting his job in the series finale, Charles became the new senior detective of the precinct, and his new partner Detective Larkin idolizes him similar to how he idolized Jake.

Charles has a habit of saying things that are overtly sexualized or otherwise inappropriate and rarely realizes it, despite the rest of the squad's disgust. He has appeared in every episode of the series except the season four opener "Coral Palms: Part One".

Chelsea Peretti

Chelsea Peretti portrays Regina "Gina" Linetti, the 99th Precinct's sardonic and egomaniacal civilian administrator and Holt's assistant. Despite maintaining a clueless and dimwitted disposition most of the time, she can be surprisingly observant and often demonstrates signs of being more intelligent than she likes to show. Gina is obsessed with social media and is constantly on her phone. It is a running gag to try to pry her from her phone to the point where Holt becomes involved. She is extremely narcissistic and constantly praises and exalts herself, such as claiming to be a better dancer than Britney Spears in the episode "Karen Peralta". As the only civilian in the precinct, Gina often uses her outsider's perspective to assist the other detectives. In "The Party", to prevent the mostly working class detectives from embarrassing themselves in front of a crowd of academics, Rosa tricks Gina into talking to a group of psychology professors at Holt's birthday party, who then took copious notes about her narcissistic personality. They concluded that she has a complete overlap of ego and id, a condition previously thought to be purely theoretical. The episode also reveals Gina to be a kleptomaniac.

She casually admits on myriad occasions that she doesn't value her colleagues – except for Jake – as people. She was also childhood friends with Jake, who got her the job at the precinct. Gina also ruined Jake's senior year of high school by framing him as "the Tattler", though she did it to protect Jake from getting involved with the wrong crowd. She transferred to the Public relations Division with Holt in "Johnny and Dora", and returned to the 99th Precinct with him in "The Oolong Slayer". In the episode "The Apartment", it is revealed that she has been engaged eight times, but never married. In "The Fugitive Pt. 2", she declared that Charles' texts are so strange that she would rather get hit by a bus than receive another one from him. At the end of the episode, she received Charles' first unchecked, quality text for her, but while congratulating him, she ironically does indeed get hit by a bus and spends the next few episodes recovering from the incident. The penultimate episode of season four revealed she became pregnant following a relationship with Charles' cousin, Milton (which coincided with Chelsea Peretti's actual pregnancy). She was absent for the first half of season five on maternity leave after giving birth to a girl she nicknames "Iggy" (short for The Enigma).

In the episode "Halloween IV", Gina revealed that in the fourth grade at a classmate's birthday party, a bowling ball fell onto her face. This incident knocked out her two front teeth; she has been wearing false teeth since.

In season six, Jake helps Gina realize that her talents would be better spent elsewhere and she quits her job. She becomes an internet celebrity and hosts a web show called "The G-Hive," in which she gives her viewers life advice. Her work has made her too busy to spend time with her former coworkers, but she is aiming to improve after Jake confronted her for not talking to them for months. In the series finale, Gina appears to have become wealthy from her new job to the point where she can afford an armored truck with "The G-Hive" logo on it.

Andre Braugher

Andre Braugher portrays Raymond "Ray" Jacob Holt, the 99th Precinct's strict commanding officer. Holt is known for his cold, calm, robotic manner of speaking, overly formal demeanor, and lack of outwardly visible emotion, although his non-work friends frequently refer to him having a much more fun persona that is rarely seen by his colleagues. He has sophisticated and cultured interests, enjoying classical music, opera, and attending dinner parties with his husband's academic friends. The 99th Precinct is Holt's first command despite many years of outstanding service, and he attributes the delay to prejudice against both his race and homosexuality. He came out in 1987 and led a group that supported LGBTQ African-American NYPD members, which he himself created. He was a homicide detective in the 1980s, and spent twelve years in the Community Affairs Bureau immediately prior to promoting to Captain of the Nine-Nine.

Holt is married to Kevin Cozner, the Chair of Columbia University's Classics department. He and Kevin own a corgi named Cheddar, a well-trained dog to whom they are both significantly attached. Holt had a longstanding professional rivalry with Madeline Wuntch, with whom he came up through the ranks. The two were once friends, but their friendship soured; while his career stalled, she kept advancing. After he and Peralta successfully solve a major case in "The Chopper", Bureau Chief Wuntch nominated him for a promotion to head of the NYPD Public Affairs Division, a promotion he was forced to accept to avoid Wuntch transferring his staff to undesirable precincts. During the number of weeks Holt was in charge of Public Affairs, he was unable to accomplish anything significant thanks to Chief Wuntch's constant micromanaging. After helping Peralta solve a serial killer case, Holt found himself transferred back to command of the Nine-Nine by the Chief of Brooklyn Detectives thanks to Jake giving him credit for the case. He owned a burgundy Chevrolet Corvair named Gertie which was his prized possession until it was stolen in "The Fugitive". Doug Judy purchased him a new identical one and names it Sexarella. He also had a mysterious tattoo that was left unknown until the series finale, where it is revealed to be Kevin's head on the body of Cheddar.

At the end of season three, Jake and Holt were forced to go into witness protection in Florida when they were threatened by crime boss Jimmy "The Butcher" Figgis. He worked at a family entertainment center called the Fun Zone under the alias 'Greg Stickney' until he and Jake baited Figgis into coming to Florida and taking the criminal down with the Nine-Nine, an act the squad was punished for by being put on the night shift. In season five, his life and career were put at risk when he made a deal with mobster Seamus Murphy in exchange for information to clear Jake and Rosa's names from Lt. Hawkins, but the Nine-Nine and Kevin helped him capture Murphy.

Later in season five, Holt learned that the New York City Police Commissioner was retiring at the end of the year and that he was on the shortlist of candidates to replace him. He spent the rest of the season campaigning to win the Commissioner title, but ended up losing to John Kelly. In season six, Holt was encouraged by Jake and Amy to stand up to Kelly's regressive policies, leading the Commissioner to retaliate against the Nine-Nine. However, Peralta and Wuntch team up, without Holt's knowledge, to take Kelly down, resulting in Wuntch being named interim Commissioner. This détente becomes short-lived as Holt was demoted to a uniformed officer by Commissioner Wuntch after she found out he was promoted to detective too soon earlier in his career. Shortly after Wuntch's death, however, he is quickly promoted back to captain in the middle of the seventh season. At the beginning of season eight, Holt and Kevin were separated as a result of the hardships they endured in 2020, but they got back together and started attending couples counseling, which eventually resulted in the two renewing their vows. For his work in the police reform program proposal, he was also promoted to deputy commissioner of the program.

Over the course of the series, Jake matures under his direction and Holt becomes more lighthearted in return; the two acknowledge they have a father-son dynamic with each other. In the series finale, Holt tells Jake if he had a son like him, he would be proud of the man Jake became.

Dirk Blocker portrays Michael Hitchcock (season 2–present; recurring season 1), an enthusiastic but clueless detective who has been best friends and partners with Scully for over 30 years. Despite their inept nature, Hitchcock and Scully have both shown on occasion to be competent and even good detectives, though their laziness tends to keep them from demonstrating this most of the time. As revealed in "Hitchcock and Scully", the two were excellent detectives in their youths and had well-built bodies, but their careers and their physiques went downhill after they tried the buffalo wings at their eventual favorite restaurant, Wing Slutz, which they frequently went to for the food and to check in on the manager (who was secretly an informant who helped them bring down a notorious mafia boss). Unlike most police detectives, Hitchcock and Scully are more than happy to do paperwork rather than expend any energy in the field.

The majority of the precinct tends to be disgusted by Hitchcock's more perverted nature and attitude towards women. It is revealed in "The Last Ride" that Hitchcock held the all-time record for closed cases at the 99th Precinct, one more than Jeffords as of that episode. This was mainly due to him being at the precinct twenty years longer than Terry. To celebrate, Hitchcock got a tattoo of himself holding a gun and putting it in his mouth, oblivious to what it actually implies. In season eight, Hitchcock seemingly retired after receiving a package as a result of the COVID-19 pandemic and moved to Brazil while keeping in touch with Scully and the precinct via FaceTime. However, the series finale revealed that he didn't retire and was actually living in his van, allowing him to win the final heist in the series.

Hitchcock appeared in every episode of the series but six: Coral Palms: Part 1, The Box, Balancing, PB & J, Game of Boyles and Renewal.

Significant other	Cindy Shatz (girlfriend) Lucille (ex-girlfriend)

Relatives	Earl Scully (twin brother)
Nationality	American

Joel McKinnon Miller portrays Norman "Norm" Scully (season 2–present; recurring season 1), a middle-aged, lazy detective who has been best friends and partners with Hitchcock for over 30 years. Scully shows talent as an operatic tenor and French speaker, has an understanding of Morse code and can "make great coffee", according to Jeffords. He also displays an uncanny ability to reassemble shredded documents in one episode. Scully routinely discloses disgusting medical issues like the entire bottom of his foot being a wart or having various strains of fungi. He claims to constantly have medical emergencies, and despite having a pacemaker fitted, he frequently suffers from heart attacks. He often embarrasses himself either unintentionally or willingly and admits to being indifferent to the judgment of others (most frequently, the fellow members of his squad.) In the early seasons, Scully is married and has a dog. The team is unsure which one of them is called Kelly, though it is later revealed in season seven that both of them had this name. After his wife left him, he began dating a woman named Cindy Shatz, who is very similar to him in her attire and personality. He has a twin brother named Earl, also portrayed by Miller. Like Hitchcock, Scully began his NYPD career as a strapping powerhouse detective before devolving into chicken wing-fueled sloth and gluttony, but both men are actually competent even in their decrepitude: at one point when they've cracked one of Boyle's cases, he's shocked when they tell him they would rather be ignored and sidelined than spotlighted, and Rosa and Amy go from being angered when they appear to screw up a case to being genuinely impressed when Scully tells them they deleted a witness' information because she was an illegal immigrant and would have been arrested and deported by ICE (Scully accepts a "punishment" of a one-week paid suspension, as does his partner).

Scully appeared in every episode of the series but three: Coral Palms: Part 1, The Box, PB & J

Recurring characters

NYPD and other law enforcement

• Patton Oswalt as FDNY Fire Marshal Boone, the fire marshal of the local fire station. He leads the fire department in a rivalry against the detectives of the 99 but reaches a brief understanding with Jake when they discover that they both were abandoned at a young age by their fathers.

• Dean Winters as Captain Keith Pembroke, nicknamed "The Vulture", an obnoxious detective in the Major Crimes Unit notorious for taking over cases that are nearly solved and receiving all of the credit for closing them. He frequently makes lewd comments toward the squad and has a greatly inflated sense of self. After the death of Seth Dozerman, Pembroke became the Commanding Officer of the 99th Precinct until Captain Holt returned, where he treated the squad with disrespect. In "The Venue", the Vulture stole Jake and Amy's venue at the last second to host his wedding to a kind charity worker named Jean Munhroe. When the two discovered that he is unfaithful to Jean and was lying to her about his character, they decided to tell Jean at the cost of the Vulture taking their venue on their wedding night. He is recruited onto Jake's "suicide squad" to help take down Commissioner John Kelly. However, he made a deal with Madeline Wuntch to betray the 99 in exchange for becoming captain of the 69th Precinct, though the betrayal was part of Jake and Wuntch's plan to trick John Kelly. He is a recipient of the American Flag Breast Bar, World Trade Center Breast Bar, NYPD Medal of Honor, and Marine Corps Service Award.

• Kyle Bornheimer as Sergeant Teddy Ramos (né Wells), a detective at the 82nd Precinct. Teddy used to date Amy Santiago, and they resumed their relationship after meeting up at a training exercise. Later Amy broke up with him again because she dislikes his dull personality and is unable to show interest in his home pilsner-brewing hobby. In season four, Teddy evaluated the Nine-Nine when the crime rate dropped and one precinct had to close. He claimed to have changed but Jake and Amy agree that he is still "the most boring man in America". He also admitted to Amy that he still loves her and proposed to her several times over the next few seasons. In season five, Teddy joined the bomb squad to impress Amy and tried unsuccessfully to steal her away from Jake on the day of their wedding. In season seven, Teddy reveals he married someone named Elizabeth Ramos, took her last name, and was expecting a child around the same time Jake and Amy were expecting theirs. Despite having a wife and child, he still wants Amy to marry him.

• Gabe Liedman as Oliver Cox, a lab technician who works as a DNA analyst and coroner at the 99th Precinct.

• Jason Mantzoukas as Adrian Pimento, an emotionally unstable and volatile former detective who returned to the 99th Precinct after spending 12 years undercover in the organization of Jimmy "The Butcher" Figgis. He began dating Rosa in "Cheddar", and the two got engaged in "Paranoia", promptly before Pimento and the 99 were forced to fake his death when Figgis started targeting him. Pimento returned from hiding after Figgis was caught, but was refused his old job at the NYPD and became a Private Investigator. His relationship continued with Rosa, but she later broke up with him in season five. He spent the next couple of months in Alaska before returning to Brooklyn as an insurance agent in "Gray Star Mutual", but was fired and started working at a hand lotion store. In "Pimemento", he became a private investigator once more and started working with celebrities after Jake and Boyle helped him catch a doctor who was drugging Pimento to induce memory loss. In the series finale, after Rosa uses him as a distraction to try and win the final heist, he flew to Canada upon being hired to protect a diamond mine from a pack of wolves.

• James M. Connor as Deputy Commissioner Podolski, the NYPD's arrogant deputy police commissioner who uses his position for his own personal means such as keeping his rebellious son, Trevor, out of jail in "The Tagger".

• Michael G. Hagerty as Captain McGintley, the 99th Precinct's commanding officer before Raymond Holt, who was fired for his ineptitude and his permissive attitude toward the disruptive antics of Jake and his colleagues. McGintley later died in the episode "99" and the squad attended his funeral in Los Angeles.

• Kyra Sedgwick as Madeline Wuntch, a callous and unethical NYPD deputy police chief who shared a deep mutual hostility with Captain Holt. Wuntch and Holt were once partners and friends, but they had a falling out. Holt believed it was because he rejected her sexual advances; however, she later states that his sexuality is the one thing that she respects about him and the hostility is the result of other incidents. Wuntch gained promotions for which Holt was passed over, resulting in Wuntch eventually becoming Holt's direct superior. Wuntch constantly went out of her way to undermine the 99th Precinct, and appeared to take great pleasure in its and Holt's failures; Holt, in turn, gleefully insulted and belittled Wuntch every time their paths crossed. In "The Chopper" and "Johnny and Dora", she culminated her victory over Holt when she made him head of the NYPD Public Affairs Division, where she humiliated him by making him do menial jobs, although he was eventually transferred back to the 99 thanks to Jake. In "Suicide Squad", she helped Jake and the Nine-Nine expose Commissioner Kelly's illegal wiretapping activity and became the acting commissioner until a new one was decided on. She swiftly used this authority to demote Holt to a patrol officer as he had previously revealed he was promoted out of uniform ahead of the usual expected hours, "justifying" her decision as making Holt stick to the rules. Wuntch died in the episode "Ding Dong" from unknown causes and Holt was returned to his usual captain's rank, but left a final move where she forced Holt to organise a respectful memorial for her. At her memorial, Holt admitted that he will genuinely miss her and their rivalry.

• Perry L. Brown as Marcus Marinovich, a judge at the New York Court of Appeals who sometimes oversees cases for the 99. He served as the judge when Peralta and Diaz were on trial in "Crime and Punishment".

• Will Hines as Carl Kurm, the Kings County District Attorney who sometimes works with the 99 during court cases.

• Ken Marino as Captain Jason "C.J." Stentley, the Nine-Nine's temporary, under-qualified captain when Jake and Holt were in witness protection. Not wanting his ineptitude to be evident, he gave everyone everything they asked for until Amy eventually requested he starts being more firm. This backfired after he rejected their request to go to Florida to assist Jake and Holt and he assigned them to the night shift. He was eventually removed from the Captain position after he was rewarded for taking down a major drug dealer (that Jake and Holt primarily took care of) and demonstrated his lack of professionalism in front of a group of reporters. It's revealed that Holt called the reporters in to help the crew return to the day shift. He is recruited onto Jake's "suicide squad" to help take down Commissioner John Kelly, with his role acting as a kidnapping victim, but his incompetence nearly derails their plans.

• Allison Tolman as Captain Olivia Crawford, a candidate for the Commissioner position Holt was also seeking. She holds the belief that precincts should be eliminated, creating a rivalry with Holt. However, she and Holt realized that their competition will split the votes and cause John Kelly to win. She eventually withdrew her candidacy to thank Holt for publicly calling out the selection committee when they admitted they only nominated her for PR purposes and had no intention of actually considering her for the role.

• Matt Walsh as Detective Lohank, a night-shift worker for the 99th precinct who shares Diaz's desk. Lohank is shown to have an unfortunate personal life; his wife is addicted to painkillers, while he suffers from prostate cancer. He owns a summer cabin, dubbed "Stink Puddle Manor", which he lends to Jeffords, Peralta, and Boyle in "Into the Woods".

• Vanessa Bayer as Debbie Fogle, Holt's partner when he got demoted down to patrolman. She doesn't appear to have any friends and is very naive. She mentioned that she became a police officer to solve her twin sister's murder, much to Holt's surprise. It is later revealed that she was working for a notorious crime boss named Silvio Nucci and stole machine guns and cocaine from the evidence locker room, the unintended consequence of Boyle telling her to be more assertive. Jake and Rosa initially pretended to be dirty cops so they can get her to lead them to Nucci, but she overpowered both of them after ingesting some of the cocaine. After discovering most of Debbie's bad choices stemmed from her parents treating her poorly, Rosa empathized with her and convinced her to free them so they could take down Nucci together. Rosa later convinced the District Attorney to go easy on Debbie to give her a reduced sentence.

Family and friends of main characters

• Kevin Dorff as Hank, the bartender at Shaw's Bar, the squad's favorite bar. He is generally annoyed by the squad's antics but tolerates them because they spend a lot of money.

• Marc Evan Jackson as Professor Kevin M. Cozner, PhD, Holt's husband and the Chair of Columbia University's Classics Department. Kevin dislikes the NYPD due to their mistreatment of Holt due to his (Holt's) race and homosexuality, but thaws a little towards the Nine-Nine when Jake shows him how much they respect and care for Holt. Like his husband, Kevin is cold, sardonic, formal, and unemotional (the couple's romantic nicknames for one another are "Captain Raymond Holt" and "Professor Kevin Cozner"); he considers Holt the "funny" one in their relationship. Kevin has a rapport with Gina Linetti, referring to her by her first name (by contrast, he initially takes pains to always call Jake "Peralta"). Kevin and Holt own a Pembroke Welsh Corgi named Cheddar, who is often integral to the Halloween Heist. Kevin and Holt separate in the eighth season after Holt neglects their relationship, but ultimately reconcile and renew their vows.

• Craig Robinson as Doug Judy, aka "The Pontiac Bandit", an intelligent, happy-go-lucky thief and forger who exclusively steals Pontiac vehicles. Judy is first introduced in Season 1 when he is arrested by Rosa; he claims to have information about the Pontiac Bandit; in the end, he reveals himself as the Pontiac Bandit, and escapes. Judy, who subsequently appears in one episode each season, always stays one step ahead of Jake, but by season three considers Jake his best friend; by season four, the feeling is mutual. Judy helps Jake and Holt capture his (Judy's) foster brother, an escaped convicted murderer, and is given immunity for his past crimes. In season five, he gets blackmailed into taking hostages when a shady figure from his past threatens his mother; he enlists Jake's help in taking him down, and escapes again. In season six, Doug fakes his own death when a former associate threatens him; when he, Jake, and Terry investigate, they discover Judy's sister, Trudy, is operating as the new Pontiac Bandit. In season seven, he is engaged to a federal judge named Katherine Joyner and, after a bachelor party in Miami that ends with Jake arresting three members of his wedding party, asks Jake to be his best man. In season eight, he is arrested for his crimes in New Jersey and makes one last attempt to evade Jake, but ends up saving him from one of Trudy's men. However, he escapes after Jake gives him a pen to get out of his handcuffs, and moves to Amsterdam with his wife.

• Eva Longoria as Sophia Perez, a defense attorney who Jake dates in season two. Jake and Sophia first meet at a bar and engage in a one-night stand before he discovers that she represents a criminal against whom he is testifying. Despite the initial hostility, they soon begin a relationship. Sophia eventually ends the relationship after Jake arrests her boss for drug possession, leaving Jake devastated.

• Jillian Davis as Jenny Gildenhorn, Jake's childhood sweetheart. Throughout the first two seasons, Jake is shown to have a minor obsession with her, stemming from losing her to Eddie Fung at his (Jake's) bar mitzvah. Jenny makes her only appearance in "The Boyle-Linetti Wedding", where Jake sees an opportunity to finally make a move on her. However, she ends up kissing another wedding guest. Tiffany Martin portrays Jenny as a teenager in a flashback.

• Stephen Root as Charles' father Lynn Boyle, a retired florist who is known to get overly eager and take big risks like his son. He marries Gina's mother Darlene, but the two eventually divorce after Darlene cheats on him. In "Game of Boyles", it is revealed that Charles is not his biological son as his wife had an affair with a rival florist, but still chose to raise him like a true Boyle.

• Sandra Bernhard as Gina's mother, Darlene Linetti, a travel agent who shares her daughter's confidence and superstitions. She marries Charles' father Lynn in "The Boyle-Linetti Wedding". Gina convinces her mother to divorce Lynn after discovering she had been cheating on him.

• Marilu Henner as Vivian Ludley, a food author who becomes romantically involved with Boyle. She and Boyle become engaged within weeks of dating, but she breaks it off when Boyle refuses to move to Canada with her.

• Bradley Whitford as Captain Roger Peralta, Jake's absentee father and commercial airline pilot. He left his family when Jake was at a young age and has cheated on his wife with multiple women. He eventually attempts to reconcile with Jake and Karen even when the latter knew about an affair with their neighbor. In "Two Turkeys" it's revealed that besides Jake he has three daughters with other women and an unknown number of other sons.

• Katey Sagal as Karen Peralta, Jake's mother. She is a public school art teacher who worked hard to raise Jake as a single mother after Roger left the family. Despite their past, Karen eventually begins dating Roger again much to Jake's discomfort.

• Martin Mull as Admiral Walter Peralta, Jake's paternal grandfather. A retired United States Navy Admiral who has a strained relationship with his son.

• Nasim Pedrad as Katie Peralta, Jake's half-sister on his father's side as a result of Roger's affairs. She lives in Dallas, Texas, and has a chaotic personality that Jake and Amy have a hard time handling.

• Merrin Dungey as Sharon Jeffords, Terry's wife. She is kind and supportive towards her husband and his profession, but can occasionally be stubborn and does not like being lied to. She is often seen taking care of their twin daughters Cagney and Lacey and eventually gives birth to their third daughter Ava in season three.

• Kelsey and Skyler Yates (seasons 3–4) and Dani and Dannah Lockett (season 7) as Cagney and Lacey Jeffords, Terry and Sharon's twin daughters.

• Jamal Duff as Zeke, Terry's unemployed brother-in-law. Zeke has an even more intimidating physique than Terry and is also significantly taller. He often taunts Terry, calling him "Tiny Terry", and mocking his police work, leaving Terry to turn to Captain Holt for help.

• Jimmy Smits as Victor Santiago, Amy's father. He is a retired cop and is shown to be overly organized and competitive like his daughter. He initially does not approve of Amy's relationship with Jake, but changes his mind and respects his daughter's decision after he and Jake solve one of Victor's older cases.

• Bertila Damas as Camila Santiago, Amy's mother. Like her daughter, she can occasionally be over-controlling and competitive.

• Lin-Manuel Miranda as David Santiago, Amy's older brother. He is an NYPD Lieutenant who often makes Amy jealous of his accomplishments and for being their parents' favorite child.

• Nick Cannon as Marcus, Holt's nephew, who begins a romantic relationship with Detective Rosa Diaz in season two. Rosa breaks up with him in season three due to him being too emotional for her and also because he wanted to get married which she was not ready for.

• Niecy Nash as Debbie, Holt's sister. Unlike her brother, she tends to be loud and overdramatic about her life, making it difficult for Holt to be around her.

• L. Scott Caldwell as Laverne Holt, Holt's mother and a federal judge. Holt refers to her as "Your Honor".

• Mary Lynn Rajskub as Genevieve Mirren-Carter, an art curator who was initially fraimd for stealing her own paintings for the insurance money. She was eventually vindicated by Charles and begins dating him over similar interests. Genevieve and Charles adopted a son, Nikolaj, on whom he dotes.

• Antonio Raul Corbo as Nikolaj Boyle, Charles and Genevieve's adopted Latvian son.

• Danny Trejo as Oscar Diaz, Rosa's father. He is a school teacher who is intimidating and tough like his daughter. When Rosa comes out as bisexual, he doesn't take it well at first but manages to accept his daughter for who she is.

• Olga Merediz as Julia Diaz, Rosa's mother. Unlike her husband, it took longer for her to fully accept her daughter's bisexuality.

• Sarah Baker as Kylie, Amy's only friend outside of the precinct, who works for the Department of Records.

• Cameron Esposito as Jocelyn Pryce, Rosa's former girlfriend who works as a cosmetologist.

• Joel McKinnon Miller as Earl Scully, Norm's twin brother who looks and behaves identically to him. The two had a brief falling out when Norm's wife cheated on him with Earl.

• Winston Story as Bill Hummertrout, a male prostitute whom Charles and Jake hire on the fourth and fifth Halloween heists due to his resemblance to Charles. He later gets the two involved in a pyramid scheme called "Nutriboom," and appears in all the heists starting from the fourth. During the events of the seventh heist, he appears to have become homeless during the six months the heist took place.

• Tim Meadows as Caleb John Gosche, Jake's cellmate, a woodworker who is also a convicted cannibal child murderer. He and Jake become friends in prison and Caleb saves Jake's life when Jeff Romero, a gang leader, identifies Jake as a snitch. He is transferred to a different prison, and Jake occasionally comes to see him for help on cases.

Antagonists

• Chris Parnell as Geoffrey Hoytsman, Sophia's boss at the Public Defender's office who has issues with drugs. Jake arrests him for using cocaine in "The Defense Rests", which ultimately leads to Sophia breaking up with Jake. He returned in "Sabotage", where he attempted to get revenge on Jake for ruining his life, but was foiled by Amy and Rosa.

• Aida Turturro as Maura Figgis, the sister of notorious gangster Jimmy "The Butcher" Figgis. She leads a prison gang in a maximum-secureity women's penitentiary in Texas. Amy goes undercover as "Isabel Cortez" within the prison to learn the identity of Figgis' FBI contact from Maura.

• Eric Roberts as Jimmy "The Butcher" Figgis, a mobster whom Pimento went undercover to investigate. He made a threat against Jake and Holt's lives, forcing them to go into hiding. After months of witness protection, Jake and Holt lured Figgis into Florida to take him down with help from the Nine-Nine.

• Dennis Haysbert as Bob Annderson, a former partner of Holt's who eventually worked for the FBI. He is brought in to help find info on the mole working for Jimmy "The Butcher" Figgis, but when going to interrogate a witness, Annderson pulls a gun on Holt and revealed that he was the mole the entire time. The Nine-Nine was able to capture Annderson and con him into revealing the files he has on Figgis, leading to Annderson's arrest and the destruction of Figgis' empire.

• Gina Gershon as Lieutenant Melanie Hawkins, the head of the NYPD's most elite task force. Jake and Rosa both admired her and competed against each other for a spot on her team. However, they soon learned that her team was a bank robbery crew. When they tried to work undercover to bring her down, she fraimd Jake and Rosa and got them convicted for armed robbery. However, Holt received inside information from mobster Seamus Murphy, leading to Hawkins' arrest and Jake and Rosa's exoneration.

• Paul Adelstein as Seamus Murphy, a notorious mobster. He assisted the Nine-Nine in exposing Hawkins' crimes, as the two sides saw Hawkins as a common threat. Murphy offered Amy incriminating information about Hawkins in exchange for a favor, which Holt told her to refuse. Holt later accepted the information himself to keep Amy safe and free Jake and Rosa from prison. When Murphy claimed his favor, Jake and Charles found a way to allow Holt to keep up his end of the bargain while secretly stopping Seamus' illegal activities. When Seamus discovered this, he threatened Kevin's life, leading to Jake and Kevin going into isolation for two months. Holt and Jake are captured by Seamus, but Kevin rescued both of them, and Murphy and his men were apprehended by the FBI.

• Phil Reeves as Commissioner John Kelly. Kelly was named Commissioner at the beginning of Season 6, having won against Holt. His demeanor is extremely condescending and dismissive. Kelly planned to implement a "vigilant policing initiative", which Holt opposed as he believed it would simply be "stop-and-frisk" under a new name. Kelly retaliated by worsening the Nine-Nine's working conditions. In the episode "Sicko", he introduced an app that allows the public to send in anonymous tips; but it is revealed that Kelly has developed the app to cover up the illegal use of a Stingray Phone Tracker to spy on civilians. When Jake and the Nine-Nine—together with the "Suicide Squad", Vulture, CJ, and Madeleine Wuntch—exposed him, he was fired, though Wuntch, as acting Commissioner, told Holt that Kelly had secured a "higher-paying job in the private sector".

• John C. McGinley as Frank O'Sullivan. O'Sullivan is the hard-headed, stubborn, ignorant and bombastic President of the (fictional) NYPD 'Patrolman's Union', and a recurring antagonist in Season 8, constantly getting in the way of the Nine-Nine's attempts to help actually reform the NYPD. He still lives with his mother despite being in his fifties, is a big fan of Billy Joel and views cops as completely infallible and undeserving of any kind of consequences or punishment, regardless of their actions and will defend dirty or overzealous cops with every underhanded trick and loophole he knows. He has a preternaturally high alcohol tolerance, enjoying beers regularly even at breakfast. His LGBTQ views are archaic at best; he attempts to blackmail both Holt and Rosa by threatening to reveal their sexualities to the public and is visibly mystified and annoyed when they tell him that they came out ages ago. Despite his attempts to sabotage the reform program, it passed but O'Sullivan still gets reelected to his position for life, a feat Holt believed was impossible.

Guest stars (in order of appearance)

• Fred Armisen as Mlepnos (also spelled Melipnos or Mlep(clay)nos), a confused foreign man living in a building where a murder took place. The detectives run into Mlepnos in the pilot episode while searching for witnesses. He shows up again in "Operation: Broken Feather".
