The Gambia River is a major river in West Africa, running 1,130 kilometres (700 mi) from the Fouta Djallon plateau in north Guinea westward through Senegal and the Gambia to the Atlantic Ocean at the city of Banjul. It is navigable for about half that length.
The river is strongly associated with the Gambia, the smallest country in mainland Africa, which consists of little more than the downstream half of the river and its two banks.
From the Fouta Djallon, the river runs northwest into the Tambacounda Region of Senegal, where it flows through the Parc National du Niokolo Koba, then is joined by the Nieri Ko and Koulountou before entering the Gambia at Fatoto. At this point the river runs generally west, but in a meandering course with a number of oxbows, and about 100 km from its mouth it gradually widens, to over 10 km wide where it meets the sea.
The aquatic fauna in the Gambia River basin is closely associated with that of the Sénégal River basin, and the two are usually combined under a single ecoregion known as the Senegal-Gambia Catchments. Although the species richness is moderately high, only three species of frogs and one fish are endemic to this ecoregion.
