The Ruvubu River (also spelt Rurubu and Ruvuvu) is a river in central Africa whose waters gather from the most distant, southern portion of the Nile basin. With a total length of 416 km (258 mi) and has a drainage basin of 14,000 km2 (5,400 sq mi). It rises in the north of Burundi, near the town of Kayanza and then does a southward arc through Burundi, being joined by the Ruvyironza River near Gitega. From there it runs northeast, through the Ruvubu National Park, up to the Tanzanian border. After a stretch along the border, the Ruvubu crosses properly into Tanzania, before joining the Nyabarongo River on the Tanzania–Rwanda border near Rusumo Falls, to form the Kagera River.
