The Ogooué (or Ogowe), also known as the Nazareth River, some 1,200 km (750 mi) long, is the principal river of Gabon in west-central Africa and the fourth largest river in Africa by volume of discharge, trailing only the Congo, Kasai and Niger. Its watershed drains nearly the entire country of Gabon, with some tributaries reaching into the Republic of the Congo, Cameroon, and Equatorial Guinea.
The source of the Ogooué River was discovered in 1894 by Mary Kingsley, an English explorer who travelled up the banks by steamboat and canoe. The river rises in the northwest of the Bateke Plateaux near Kengue, Republic of Congo. It runs northwest, and enters Gabon near Boumango. Poubara Falls are near Maulongo. From Lastoursville up to Ndjole, the Ogooué is non-navigable due to rapids.
From the latter city, it runs west, and enters the Gulf of Guinea near Ozouri, south of Port Gentil. The Ogowe Delta is quite large, about 100 km long and 100 km wide.
