Koo Wee Rup /ˌkuː ˌwiː ˈrʌp/ is a town and satellite suburb in Victoria, Australia, located 63 km south-east of Melbourne's Central Business District, located within the Shire of Cardinia local government area.

The town previously hosted an annual potato festival each March to raise funds for the Westernport Memorial Hospital, now known as Kooweerup Regional Health Service.

A lesser-known historical fact about Koo Wee Rup is that in 1921–1922, the Amalgamated Wireless Limited company established an experimental radio receiving station in the area.

This facility was capable of receiving transmissions directly from Europe without the need for relay stations in other countries, marking a significant advancement in international communication.

However, since the closure of the South Gippsland rail line by the Kennett state government on 14 December 1994, the South and West Gippsland Transport Group, represented by the local council, have campaigned for the rail service to be reinstated beyond its current terminus at Cranbourne by the 2020s,[3] which had been promised by the Bracks government on its election in 1999.
