The Oṣun River, Yoruba: Odò Ọ̀ṣun, is a river of Yorubaland that rises in Ekiti State and flows westwards into Osun State before turning southwestwards at its confluence with the Erinle River near the town of Ede and then heading south at the Asejire reservoir flowing though the rest of the state and Ogun State in Southwestern Nigeria before eventually discharging into the Lekki Lagoon and the Atlantic at the Gulf of Guinea.
