The Tsavo River runs east from the western end of the Tsavo National Park of Kenya
, near the border of Tanzania
, until it joins with the Athi River, forming the Galana River near the center of the park. This river is the main contributor to the watershed of the lower portion of the park region, and is home to abundant fish. The Tsavo River is the site of the 1898 Tsavo Maneaters incident.
