In the Yorubá religion, Olokun is the Orisha (a deity who is the embodiment and the very spirit of a force of nature) of all bodies of water but mostly of the depths of the sea. He is seen by the Yorubá as male, female by the Ifé or sometimes both. Olokun is as mysterious as the bottoms of the sea and also is the keeper of the riches of the ocean.

In Candomblé and Umbanda religions in Brazil, Olokun is such a secretive and mysterious Orixá, that his worship is made through Yemanjá, both considered to be aspects of one another.
All life sprang from his waters. In one legend though, he got so enraged with Olorum, that to demonstrate his powers, he caused the great deluge and to constrain his wrath he had to be chained in the bottom of the sea.

Olokun is so powerful that he is the second most important Orixá. His attributes are mystery, power, strength, wealth, and health.
