The Coleman River is a river on the Cape York Peninsula in Far North Queensland, Australia.
Formed by the confluence of the Little Coleman River and Big Coleman River, the headwaters of the river rise under Lapunya Mount near The Lagoons in the Great Dividing Range and initially flows south. It flows past the Curlew Range and then turns west across the Boomerang Plain eventually discharging into the Gulf of Carpentaria between the mouth of the Mitchell River to the south and the settlement of Pormpuraaw to the north. From source to mouth, the Coleman River is joined by six tributaries including the King River and the Lukin River, and descends 234 metres over its 399-kilometre.
The catchment includes the Edward River sub-basin, and area occupies 737.6 square kilometres.
A total of 46 species of fish have been found in the river, including: the sailfin glassfish, barred grunter, shovel-nosed catfish, bigeye trevally, fly-specked hardyhead, golden gudgeon, pennyfish, mouth almighty, barramundi, oxeye herring, rainbowfish and seven-spot archerfish.
