The Yoruba religion (Yoruba: Ìṣẹ̀ṣe), West African Orisa (Òrìṣà), or Isese (Ìṣẹ̀ṣe), comprises the traditional religious and spiritual concepts and practice of the Yoruba people. Its homeland is in present-day Southwestern Nigeria, which comprises the majority of Oyo, Ogun, Osun, Ondo, Ekiti, Kwara and Lagos states, as well as parts of Kogi state and the adjoining parts of Benin and Togo, commonly known as Yorubaland (Yoruba: Ilẹ̀ Káàárọ̀-Oòjíire).

It shares some parallels with the Vodun practiced by the neighboring Fon and Ewe peoples to the west and with the religion of the Edo people to the east. Yoruba religion is the basis for a number of religions in the New World, notably Santería, Umbanda, Trinidad Orisha, and Candomblé. Yoruba religious beliefs are part of Itàn (history), the total complex of songs, histories, stories, and other cultural concepts which make up the Yoruba society.
