Sydney Olympic Park is a suburb of Greater Western Sydney, located 13 kilometres west of the Sydney central business district, in the local government area of the City of Parramatta Council. It is commonly known as Olympic Park but officially named Sydney Olympic Park. The area was part of the suburb of Lidcombe and known as "North Lidcombe", but between 1989 and 2009 was named "Homebush Bay". The names "Homebush Bay" and, sometimes, "Homebush" are still used colloquially as a metonym for Stadium Australia as well as the Olympic Park precinct as a whole, but Homebush is an older, separate suburb to the southeast, in the Municipality of Strathfield.
