This is a list of streams and rivers in South Sudan, arranged geographically by drainage basin. There is an alphabetic list at the end of this article. The list may not be comprehensive.

The hydrology of the eastern part of South Sudan is complicated by the Sudd, a vast area of marshland into which many rivers flow and lose their identity. Much of the water entering the Sudd is lost to evaporation, but much ultimately drains to the White Nile. Ninety percent of South Sudan lies in the White Nile basin[1] The three major cities of South Sudan are all located on the White Nile or a major tributary.
