The Uele, also known by the phonetically identical Uélé, Ouélé, or Welle River,[1][2] is a river in the Democratic Republic of the Congo.

The Uele forms at Dungu, at the confluence of the Dungu and Kibali rivers, which both originate in the mountains near Lake Albert.

Combined these rivers flow west for about 1,210 kilometres (750 mi), until the Uele joins the Mbomou River at Yakoma.

The Uele–Mbomou confluence at Yakoma marks the origin of the Ubangi River, which in turn flows into the Congo River.

The Uele is the longest tributary of the Ubangi.
