The Niger River (/ˈnər/ NY-jərFrench(le) fleuve Niger [(lə) flœv niʒɛʁ]) is the main river of West Africa, extending about 4,180 km (2,600 mi). Its drainage basin is 2,117,700 km2 (817,600 sq mi) in area.[9] Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border.[10][11] It runs in a crescent shape through MaliNiger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta[12] (or the Oil Rivers), into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded by the Nile and the Congo River. Its main tributary is the Benue River.
