Macquarie Park (/məˈkwɒri/) is a suburb in the Northern Sydney region of Sydney, New South Wales, Australia. Macquarie Park is located 13 kilometres north-west of the Sydney central business district in the local government area of the City of Ryde. Macquarie Park was part of the suburb of North Ryde until it was gazetted as a suburb in its own right on 5 February 1999, and many businesses still use North Ryde as the address. Both suburbs share the 2113 postcode but Macquarie University, which is located at the northern part of the suburb, has its own postcode of 2109.
