The Huon River (/ˈhjuːɒnˈrɪvə/ HYOO-on-RIV-ə, Mellukerdee/palawa kani: Taloonne) is a perennial river in the southwest and southeast regions of Tasmania, Australia. At 174 kilometres (108 mi) long, the Huon River is the fifth-longest in the state, with its course flowing east through the fertile Huon Valley and emptying into the D'Entrecasteaux Channel, before flowing into the Tasman Sea.

At its mouth, the Huon River is over 5 kilometres (3 mi) wide, and in the lower reaches, the river's average depth is 3 metres (10 ft), with maximum depths of up to 12 metres (39 ft). The Egg Islands, in this lower tidal zone, are ecologically significant for their rich wetlands and birdlife.

The Huon River was historically a transportation route for early settlers, the timber industry, and agricultural goods. The development of roads in the Huon Valley over the 19th century eventually overtook the river as the primary transport route.
