10. Niger River – 4,180 km (2,600 miles)
The Niger River is the principal river in West Africa, extending for approximately 4,180 km (2,600 mi). The drainage basin occupies an area of 2,117,700 km2 (817,600 sq mi). Its source is in the Guinea Highlands in southeastern Guinea, near the Sierra Leone border.
Niger runs across the Gulf of Guinea into the Atlantic Ocean as the Niger Delta (or oil rivers), taking a vacation through a large-scale delta through Mali, Niger, and then through Nigeria, along the border with Benin.
Niger is the third longest river in Africa. It is more than just the Nile and the Congo River (also known as the Zaire River). Its main tributary is the Benue River. The Niger River ranks tenth among the top 10 longest rivers in the world.
