Flinders is a seaside town on the Mornington Peninsula in Melbourne, Victoria, Australia, 73 km (45 mi) south of Melbourne's Central Business District, located within the Shire of Mornington Peninsula local government area. Flinders recorded a population of 1,130 at the 2021 census.

Flinders is located at the point where Western Port meets Bass Strait.

The town was named by George Bass after his friend, the explorer and British naval officer Matthew Flinders.^{[citation needed]} Settlement commenced in 1854 and many pioneers and settlers are buried at the Flinders cemetery. Flinders Post Office opened on 7 March 1863 as the population grew.

Flinders was once believed to have previously been known as Mendi-Moke, but this has subsequently been denied.

Features of the town include the Flinders Golf Club, a picturesque golf course built on a cliff top, a recreation reserve, a small yacht club, and a 250 metres (820 ft) long pier out from the protected beach, sheltered from the waters of Bass Strait by West Head. This area is popular for sailing, fishing, and other watersports.

On the southern side of West Head, the ocean breaks over the basalt rocks of Mushroom Reef Marine Sanctuary at Flinders ocean beach. Mushroom Reef hosts one of Victoria's best intertidal and subtidal rock platform reefs, popular for beachcombing, recreational diving, snorkelling, and surfing. Several accommodation options exist, including B&Bs and hotel-motel style accommodation. Shopping and a mobile library are also available to tourists and residents.

Flinders was the original home of Flinders Bread, available throughout Melbourne and the Mornington Peninsula. The company's operations are now based in Dandenong, but the bread is still available locally.

The Royal Australian Navy operate a weapons training facility and gunnery on West Head, with public access to this area being restricted.^{[citation needed]}
