Buckingham River

Buckingham River is a river in the Northern Territory of Australia. The headwaters of the river are on the northern edge on the eastern side of the Mitchell Ranges near where the Central Arnhem Road crosses the Range. The river flows in a northerly direction though uninhabited country until it discharges into Buckingham Bay and the Arafura Sea.

The estuary formed at the river mouth is tidal in nature and in near pristine condition.

The catchment area of the river is 7510 km2 and has an annual average discharge of 2330 GL.

The traditional owners of the area are the Murngin also known as the Yolngu peoples. The Aboriginal community of Gapuwiyak still has supplies taken by barge up the river to be delivered. The community is 20 km by road from the landing.
