Bonython Park is a 17-hectare park in the north-west Park Lands of the South Australian capital of Adelaide. The park was opened in 1962 and named in honour of prominent South Australian politician and journalist, Sir John Langdon Bonython. It is situated on the north-western side of the River Torrens, bordered by Port Road. It is on the opposite side of the river to a golf course, and adjacent to the old Adelaide Gaol and the Police Barracks.

The Adelaide Park Lands comprise the figure-eight configuration of land, spanning both banks of the River Torrens between Hackney and Thebarton, which encloses and separates the City of Adelaide area from the surrounding suburbia of greater metropolitan Adelaide, the capital city of South Australia. They were laid out by Colonel William Light in his design for the city, and originally consisted of 2,300 acres (930 ha) "exclusive of 32 acres (13 ha) for a public cemetery". One copy of Light's plan shows areas for a cemetery and a Post and Telegraph Store on West Terrace, a small Government Domain and Barracks on the central part of North Terrace, a hospital on East Terrace, a Botanical Garden on the River Torrens west of North Adelaide, and a school and a storehouse south-west of North Adelaide.
