St. Augustine Catholic Church (Isle Brevelle) is outside Natchitoches, Louisiana, USA. Tradition holds that the church was established by Nicolas Augustin Métoyer, a newly freed slave, in 1803 and that services have been held continuously since then. The congregation may have gathered then, but the church and priest came later. As is often the case, historical records challenge the local lore. Parish records document the founding of the Chapel of St. Augustine “as a mission of the church of St. François of Natchitoches” in July 1829, when the church was constructed. It did not become a parish church with a resident priest until 1856.
The church is included in the Cane River National Heritage Area. Because of the significance of the church and the Créole community, it is listed on the Louisiana African American Heritage Trail.
