Americus (foaled 1892, died 1910), was an American Thoroughbred racehorse who was exported to England. He had some success as a racehorse, but was more notable for his influence at stud. He was bred in California and won the 1895 Culver Stakes prior to his export. He continued to race in England, until he was nine years old, while also standing as a breeding stallion. He stood at stud in Italy, Ireland, Germany, and Belgium before dying in Germany in 1910. Americus' most famous descendant was his great-granddaughter Mumtaz Mahal.
