The longest river in Africa is the Nile River, which a runs a total distance of 4,160 miles. The Nile River is also the longest river in the world.
The Nile River proper begins near the city of Khartoum in the African country of Sudan, where the White Nile and the Blue Nile, the two main sources of the river, combine to form the Nile. From that point, the river travels north through Sudan and Egypt, eventually depositing its water in the Mediterranean Sea along the Egyptian coast. The river has an average discharge of 99,941 cubic feet of water per second. Other countries through which the Nile tributaries flow include Tanzania, Uganda, Rwanda, Burundi, Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea and South Sudan.
