The Mistick Krewe of Comus, founded in 1856, is a New Orleans, Louisiana Carnival krewe. It is the oldest continuous organization of New Orleans Mardi Gras festivities. Prior to the advent of Comus, Carnival celebrations in New Orleans were mostly confined to the Roman Catholic Creole community, and parades were irregular and often very informally organized. Comus was organized by (largely Protestant) Anglo-Americans.
