Traditional religions

It is unclear to what extent indigenous beliefs, such as the Serer religion, continue to be practised. Serer religion encompasses cosmology and a belief in a supreme deity called Roog. Some of its religious festivals include the Xooy, Mbosseh, and Randou Rande. Each year, adherents of Serer religion make the annual pilgrimage to Sine in Senegal for the Xooy divination ceremony. Serer religion also has a rather significant imprint on Senegambian Muslim society in that Senegambian Muslim festivals such as "Tobaski", "Gamo", "Koriteh" and "Weri Kor" have names representing loanwords from the Serer religion – they were ancient Serer festivals.

Like the Serers, the Jola people have their own religious customs, including a major religious ceremony, Boukout.
