The Sobat River is a river in Sudan, Africa. The most southernly of the great eastern tributaries of the Nile, the Sobat enters the White Nile at Dolieb Hill, near the city of Malakal in the Upper Nile state of Sudan. The Sobat River is formed by the confluence of the west-flowing Baro River and the north-flowing Pibor River, on the border with Ethiopia.

When in flood the Sobat River produces an enormous discharge carrying a white sediment, which gives the White Nile its name.[1]

The Sobat and its tributaries drain a watershed approximately 225,000 km² (87,000 sq mi) in size. The river's mean annual discharge is 412 m³/s (14,550 ft³/s).[2]
