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 one mile (1609.344 m) in length and one and half chains (30.1752 m) in width. It is named for the explorer Matthew Flinders, who was (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. As the closest street to the river, Flinders Street serviced Melbourne's original river port.
