The Sobat River is a river of the Greater Upper Nile region in northeastern South Sudan, Africa.

The river enters the White Nile at Doleib Hill, near the city of Malakal in Upper Nile State.

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.
