Location of the mouth of the Yarra River in Victoria

The Yarra River or historically, the Yarra Yarra River, (Aboriginal: Berrern, Birr-arrung, Bay-ray-rung, Birarang,Birrarung, and Wongete) is a perennial river in east-central Victoria, Australia.

The lower stretches of the river are where the city of Melbourne was established in 1835 and today Greater Melbourne dominates and influences the landscape of its lower reaches. From its source in the Yarra Ranges, it flows 242 kilometres (150 mi) west through the Yarra Valley which opens out into plains as it winds its way through Greater Melbourne before emptying into Hobsons Bay in northernmost Port Phillip.

The river was a major food source and meeting place for indigenous Australians from prehistoric times. Shortly after the arrival of European settlers land clearing forced the remaining Wurundjeri to neighbouring territories and away from the river. Originally called Birrarung by the Wurundjeri, the current name was mistranslated from another Wurundjeri term in the Boonwurrung language; Yarro-yarro, meaning "ever-flowing".

The river was utilised primarily for agriculture by early European settlers. The landscape of the river has changed dramatically since 1835. The course has been progressively disrupted and the river widened in places. The first of many Crossings of the Yarra River to facilitate transport was built in Princes Bridge. Beginning with the Victorian gold rush it was extensively mined, creating the Pound Bend Tunnel in Warrandyte, and the Big and Little Peninsula Tunnels above Warburton. Widening and dams, like the Upper Yarra Reservoir have helped protect Melbourne from major flooding. The catchment's upper reaches are also affected by logging. Industrialisation ultimately led to the destruction of the marshlands at the confluence of the Yarra and Maribyrnong Rivers in the area around Coode Island in West Melbourne.
