ST. MARY PARISH LOUISIANA

St. Mary Parish was part of the original Attakapas region when the United States purchased Louisiana from the French.  It was created as a separate parish from St. Martin Parish in 1811.  The Chitimacha were the original inhabitants of the area.  They received federal tribal recognition in 1918. Of St. Mary’s 555 square mile land area, the Chitimacha Reservation covers approximately 283 acres near the community of Charenton. The parish is bounded by St. Mary and Terrebonne Parishes to the south, Iberia along its western border, Iberia and St. Martin to the north, and Assumption and Terrebonne to the east. The parish was named for St. Mary.
