OgunOkoỌya (Yorùbá: Ọya, also known as Oyá or Oiá; Yàńsàn-án or Yansã; and Iansá, Iansã, or Iansan in Latin America) is an Orisha of winds, lightning, and violent storms.

Ọya lived on Earth as a human from the town of Ira, in present day Kwara state, Nigeria, where she was a wife of the Alaafin of Oyo, Shango.

In Yorùbá, the name Ọya is believed to derive from the phrase coined from "ọ ya" which means "she tore," referring to her association with powerful winds.

[4] In the Yoruba religion, Ọya was married three times, first to the warrior orisha Ogun, then Shango, and finally, another hunting and farming deity, Oko.

A simple, unseasoned form of acarajé is used in rituals and a version served with various condiments is sold as a common street food in Bahia in the northeast of Brazil.
