Flinders Street is a notable street in Melbourne, Victoria, Australia. Running roughly parallel to the Yarra River, Flinders Street forms the southern edge of the Hoddle Grid. It is exactly 1 mi (1.609 km) in length and one and a half chains (99 ft, 30 m) in width. It is named for the explorer Matthew Flinders, erroneously credited with discovering Port Phillip at the time of its naming. It extends eastwards as far as Spring Street and the Treasury Gardens and westwards past Batman's Hill to the Melbourne Docklands.

Tram routes 70 and 75, as well as the City Circle route, run along Flinders Street, and the Flinders Street Viaduct runs parallel to the street, linking the city's two major railway stations.
