Prospect Creek is an urban watercourse of the Georges River catchment that is located in the western region of Sydney, in New South Wales, Australia.

[1] The catchment area of the creek is approximately 98 square kilometres (38 sq mi), and is largely urbanised with industrial land uses, residential and open space for recreation.

[3] In 2023, Sydney Water Corporation was convicted and fined $200,000 in the Land and Environment Court of NSW after 282,000 litres of sewage was spilled into the creek.

Areas within the Prospect Creek Catchment include, Fairfield City (65.6%), Cumberland Council (13.7%), Bankstown (10.5%), Blacktown (7.8%) and Liverpool (2.4%).

[8] In September 2020, this proposal went before the Geographical Names Board of NSW (GNB) after Community Advocate Lachlan Hyde with the support of local state MPs[9] pushed the New South Wales Government on the matter.
