Centennial Park is a suburb split between the local government area of the City of Sydney and the City of Randwick, located 4 kilometres (2.5 mi) east from the Sydney central business district, in the eastern suburbs of Sydney in the state of New South Wales, Australia.

Centennial Park is home to a number of wild animals including birds, rabbits, and foxes. It is also home to a number of equestrian schools and other domestic animal endeavours such as the Centennial Park Rabbit Retreat,^[2] a boarding facility for rabbits in the Centennial Park and Paddington area.

The western fringe of the suburb is used for residential purposes and is within the City of Sydney. It features quality houses on large blocks as well as large multi-unit buildings. The bulk of the suburb consists of the Centennial Parklands (from which the suburb takes its name) and is within the City of Randwick. The parklands extend further partly into the suburb of Queens Park, adjacent to (but separate from) the park of the same name in that suburb.^[3]

Centennial Park started out as a reserve to protect the central ponds and swamps which formed early Sydney's water supply. When it was superseded by the Nepean water supply system in the 1880s it was decided to create a large park, which opened as Centennial Park in 1888. Part of the funding was to come from selling off residential lots adjacent to the park, but this did not occur until 1904 when 101 acres (41 ha) of land along the western border was subdivided. To ensure high standards of residential development, strict requirements were imposed. No wooden buildings or terrace homes were allowed; brick or stone were mandated, with tile or slate roofs. Between 1905 and 1925, a wide range of substantial, quality homes were built, featuring a mixture of Federation, Arts and Crafts, Victorian and Old English styles. The streets created were Martin Road, Robertson Road, Lang Road and Cook Road.^[4] Sections of the park were to be cleared in the 1970s for a sports complex but the project was called off after the NSW Builders Labourers Federation placed a green ban in response to a request from park users.^[5]
