Lakes
- Lake Kivu, between Rwanda and the Democratic Republic of Congo to the west, is by far the largest
- Lake Muhazi, about twenty kilometres east of Kigali: a long, narrow lake running roughly east–west and extending north and south into a number of tributary valleys
- Lake Ihema, in the Akagera National Park in the far east of the country, by the border with Tanzania
- Lake Rweru in the south-east, which is shared with Burundi
- Lake Burera, a mountain lake in the north (1862 metres above sea level)
- Lake Ruhondo, just to the south of Lake Burera, separated from it by a spine of hills
- Lake Mugesera, about 30 km south-east of Kigali, is a narrow lake consisting of five east–west bays joined at the western side
- Lake Cohoha South, south of Kigali on the border with Burundi
There are a number of smaller, shallow lakes in the flat, swampy region between Lake Mugesera and Lake Rweru.
