Louisiana Voodoo, also known as New Orleans Voodoo, is an African diasporic religion that originated in Louisiana. It arose through a process of syncretism between the traditional religions of West Africa, the Roman Catholic form of Christianity, and Haitian Vodou. No central authority is in control of Louisiana Voodoo, which is organized through autonomous groups.

African diaspora religions, also described as Afro-American religions, are a number of related beliefs that developed in the Americas in various nations of the Caribbean, Latin America and the Southern United States. They derive from traditional African religions with some influence from other religious traditions, notably Christianity and Islam.
