The Oba River (Yoruba: Odo Ọba) is a river in Oyo and Osun States in Nigeria. It is the main tributary of the Osun River. The landscape varies from wooded savanna in the north to rain forest in the south. The river is heavily polluted. Most of the people who live along its length practice farming and fishing.
