The Huon River is a perennial river located in the south-west and south-east regions of Tasmania, Australia. At 174 kilometres in length, the Huon River is the fifth-longest in the state, with its course flowing east through the fertile Huon Valley and emptying into the DEntrecasteaux Channel, before flowing into the Tasman Sea.
At its mouth, the Huon River is over 5 kilometres wide, and in the lower reaches, the rivers average depth is 3 metres, with maximum depths of up to 12 metres. The Egg Islands, located in this lower tidal zone, serve as a significant ecological area due to 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.
