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. It is a sacred and reserved area where dirt and other unlawful activities are not meant to take place.
