St. Augustine Catholic Church and Cemetery (Natchez, Louisiana)

St. Augustine Catholic Church and Cemetery, or the Isle Brevelle Church, is a historic Catholic parish property founded in 1829 near Melrose, Natchitoches Parish, Louisiana. It is the cultural center of the Cane River area's historic French, Spanish, Native American and Black Creole community. It is also the oldest surviving Black Catholic church in the United States.

Established as a mission church by Louisiana Creole Nicolas Augustin Metoyer, St. Augustine is celebrated as the first church in Louisiana to be built by and for free people of color. It is also among the oldest churches founded and built by and for African Americans.

The church and cemetery are within the Cane River National Heritage Area, and are listed on the National Register of Historic Places. Because of its significance in Catholic and Creole history, St. Augustine also is a marked destination on the Louisiana African American Heritage Trail.
