The Oṣun River (sometimes, but rarely spelt Oshun) is a river that flows southwards through central Yorubaland in southwestern Nigeria into the Lagos Lagoon and the Atlantic Gulf of Guinea. It is one of the several rivers ascribed in local mythology to have been women who turned into flowing waters after some traumatic event frightened or angered them.

Der Osun (Ọṣun, Oshun) ist ein Fluss im Südwesten Nigerias. Er ist nach Osun benannt, die in der Religion der Yoruba die Flussgöttin darstellt.
