The Yabus River (or Khor Yabus) rises in the far west of Ethiopia, in Asosa Zone, flows west into Sudan past the town of Yabus, then enters South Sudan. At the town of Boing it turns south west and enters the Machar Marshes, where it loses its identity.
The river is sometimes confused with the Dabus River, a tributary of the Blue Nile, also known as the Yabus River. The sources of the two rivers are close to each other.
Yabus is linked by road to Kurmuk some 80km to the north, but the road is only passable in the dry season.
There is an airport at Yabus.
A number of humanitarian agencies have been active in Yabus, including GOAL (of Ireland), ROOF (Relief Organization of Fazugli, Nairobi), CEAS (Church Ecumenical Action in Sudan) and SIM (Serving In Mission).
The area is disputed between Sudan and South Sudan. In May 2011 it was reported that the Sudan People's Liberation Army was occupying Yabus, and the army of Sudan was threatening to occupy it. As a result, humanitarian agencies had to withdraw from the area.
