The Flinders River is the longest river in Queensland, Australia, at approximately 1,004 kilometres. It was named in honour of the explorer Matthew Flinders. The catchment is sparsely populated and mostly undeveloped. The Flinders rises on the western slopes of the Great Dividing Range in North West Queensland and flows generally north-west through the Gulf Country, across a large, flat clay pan, before entering the Gulf of Carpentaria.
The River rises in the Burra Range, part of the Great Dividing Range, 110 kilometres north-east of Hughenden and flows in a westerly direction past Hughenden, Richmond and Julia Creek, then north-west to the Gulf of Carpentaria 25 km west of Karumba. The catchment is bordered to the south by the Selwyn Range.
At 1,004 kilometres in length, it is the eighth-longest river in Australia. The catchment covers 109,000 square kilometres. The primary land use in the catchment is grazing and other agriculture, the catchment covers 1.5% of the continent.
There are two dams on the river - the Flinders River Dam and Corella Dam.
