The Nyabarongo River Wetlands is a protected area in Rwanda, covering 142.62 km². It is located in the south-east of the country, south-east of Kigali, and includes swamps and marshes in part of the flood-plain of the Nyabarongo river, the longest river in Rwanda.
The wetlands are hydrated by the Nyabarongo River, a tributary of the Nile, which empties into the Akagera River which, in turn, flows into Lake Victoria. Nyabarongo River is believed to be the source of the mighty River Nile according to some sources.
The vegetation is composed of Cladium and Typha, Cyperus latifolius, Cyperus papyrus and Echninochloa pyramidalis. Average annual rainfall is estimated to be 950–1,100 mm
