Louisiana Voodoo, also known as New Orleans Voodoo originated from the ancestral religions of the African diaspora. A cultural form of the Voodoo religions which historically developed within the French- and Creole-speaking African-American population of the U.S. state of Louisiana. It is one of many incarnations of African-based religions rooted in the West African Dahomean Vodou tradition, and the Central African traditions that can be found in Haitian Vodou, syncretized with the Catholic religion via the slave trade.

Louisiana Voodoo is often confused with – but is not completely separable from – Haitian Vodou and southeastern U.S. hoodoo. While it generally shares the same loa as Haitian Vodou, it lays a generally greater emphasis upon folk magic (as does hoodoo). This emphasis has become a spiritocultural marker for southern, Afro Diaspora, francophone Louisiana within the Western media, as it was through Louisiana Voodoo that such terms as gris-gris (an Ewe term) and voodoo dolls were introduced into the American lexicon.
