Greenacre is a suburb in South-western Sydney, located 20 kilometres south-west of the Sydney central business district in the state of New South Wales, Australia. Most of Greenacre is in the local government area of the City of Canterbury-Bankstown, while a part in the east is in the Municipality of Strathfield.
 This area was previously known as East Bankstown. When the first road went through the area, an acre of land was cleared for cultivation. The contrast to its surrounding area led to it being referred to as the 'Green Acre'. In 1909, Greenacre Park Estate became one of the first subdivisions in the area. Michael Ryan operated an inn called the Harp of Ould Erin on land he owned to the north of Liverpool Road.
 The eastern part of the suburb, east of Roberts Road and north of Juno Parade, was mostly part of the large logistical and industrial area surrounding Enfield Marshalling Yards, with a small residential area. This area was incorporated into Enfield Council in 1889, and transferred to Strathfield Council in 1949 along with the western ward of Enfield Council (most of which is now Strathfield South).[citation needed]
 A separate part of the suburb, north of Liverpool Road (Hume Highway), is also railway and industrial land, and was added to Strathfield Council in 1892.
