Oshun, is an Orisha, a spirit, a deity, or a goddess that reflects one of the manifestations of the Yorùbá Supreme Being in the Ifá oral tradition and Yoruba-based religions of West Africa. She is one of the most popular and venerated Orishas. Oshun is an important river deity among the Yorùbá people. She is the goddess of divinity, femininity, fertility, beauty and love. She is connected to destiny and divination.

During the life of the mortal Osun, she served as queen consort to King Shango of Oyo. Following her posthumous deification, she was admitted to the Yoruba pantheon as an aspect of a primordial divinity of the same name.

She is the patron saint of the Osun River in Nigeria, which bears her name. The river has its source in Ekiti State, in the west of Nigeria, and passes through the city of Osogbo, where Osun-Osogbo Sacred Grove, the principal sanctuary of the deity, is located.
