The Roman Catholic Archdiocese of New Orleans (Latin: Archidioecesis Novae Aureliae, French: Archidiocèse de la Nouvelle-Orléans, Spanish: Arquidiócesis de Nueva Orleans) is an ecclesiastical division of the Roman Catholic Church spanning Jefferson (except Grand Isle), Orleans, Plaquemines, St. Bernard, St. Charles, St. John the Baptist, St. Tammany, and Washington civil parishes of southeastern Louisiana. It is the second to the Archdiocese of Baltimore in age among the present dioceses in the United States, having been elevated to the rank of diocese on April 25, 1793, during Spanish colonial rule. Its patron saints are the virgin Mary under the title of Our Lady of Prompt Succor and St. Louis, King of France, and Cathedral Basilica of Saint Louis is its mother church with St. Patrick's Church serving as a pro-cathedral. The archdiocese has 137 church parishes administered by 387 priests (including those belonging to religious institutes), 187 permanent deacons, 84 brothers, and 432 sisters. There are 372,037 Catholics on the census of the archdiocese, 36% of the total population of the area. The current head of the archdiocese is Archbishop Gregory Michael Aymond. The Roman Catholic Archdiocese of New Orleans reflects the cultural diversity of the city of New Orleans and the surrounding (civil) parishes. As a major port, the city has attracted immigrants from around the world. When French and Spanish Catholics ruled the city, some encouraged enslaved Africans to adopt Christianity, resulting in a large population of African American Catholics with deep heritage in the area. Later, Irish, Italian, Polish, Bavarian, and other immigrants have brought their heritage and customs to the archdiocese. The last quarter of the 20th century also brought many Vietnamese Catholics from South Vietnam to settle in the city. New waves of immigrants from Mexico, Honduras, Nicaragua and Cuba also have added to the Catholic population. The Roman Catholic Archdiocese of New Orleans is also a metropolitan see of a province that spans the entire U.S. state of Louisiana. Its suffragan sees are the Diocese of Alexandria, Diocese of Baton Rouge, Diocese of Houma-Thibodaux, Diocese of Lafayette in Louisiana, Diocese of Lake Charles, and Diocese of Shreveport.
