Antonio de Sedella, O.F.M. Cap. (1748-19 January 1829) was a Spanish Capuchin friar who served as the leading religious authority of the Catholic Church in New Orleans, Louisiana, during the late 18th and early 19th centuries. Commonly called Père Antoine, he has become a noted figure in the culture of the city. His ghost is said to walk an alley now named for him which runs alongside the city's cathedral. A street and a restaurant in the city's historic French Quarter are named for him.
