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 administered from New Orleans, Louisiana. It is the second-oldest diocese in the present-day United States, having been elevated to the rank of diocese on April 25, 1793, by Pope Pius VI during Spanish colonial rule. Our Lady of Prompt Succor and St. Louis, King of France are the patron saints of the archdiocese and Cathedral Basilica of Saint Louis is its mother church as St. Patrick's Church serves as the Pro-Cathedral of the archdiocese.
Led by an archbishop, the Archdiocese of New Orleans is the center of a larger ecclesiastical province that encompasses the entire state of Louisiana. The Metropolitan Province of New Orleans include the suffragan Dioceses of Alexandria, Baton Rouge, Houma-Thibodaux, Lafayette, Lake Charles, and Shreveport.
On June 12, 2009, Pope Benedict XVI named Bishop Gregory Michael Aymond of the Diocese of Austin to be Archbishop of New Orleans. Archbishop Aymond was installed on August 20, 2009 at Saint Louis Cathedral.
The archdiocese encompasses eight civil parishes in the New Orleans metropolitan area: Jefferson, Orleans, Plaquemines, St. Bernard, St. Charles, St. John the Baptist, St. Tammany, and Washington. There are 137 church parishes in the archdiocese, ministered 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. There is one Archbishop Emeritus: Archbishop Alfred Clifton Hughes. There is also one Auxiliary Bishop Emeritus: Bishop Dominic Carmon, S.V.D.
The Catholic Church has had a presence in New Orleans since before the founding of the city by the French in 1718. Missionaries served the French military outposts and worked among the native peoples. The area was then under the jurisdiction of the Bishop of Quebec. In 1721 Fr. Francis-Xavier de Charlevoix, S.J., made a tour of New France from the Lakes to the Mississippi, and visiting New Orleans, he describes "a little village of about one hundred cabins dotted here and there, a large wooden warehouse in which I said Mass, a chapel in course of construction and two storehouses".
In 1722 the Capuchins were assigned ecclesiastical responsibility for the Lower Mississippi Valley, while the Jesuits maintained a mission, based in New Orleans, to serve the indigenous peoples. The Jesuit vicar-general returned to France to recruit priests and also persuaded the Ursulines of Rouen to assume charge of a hospital and school. The royal patent authorizing the Ursulines to found a convent in Louisiana was issued 18 September, 1726. Ten religious from various cities sailed from Hennebont on 12 January, 1727, and reached New Orleans on 6 August. As the convent was not ready, the governor gave up his residence to them. They opened a hospital for the care of the sick and a school for poor children.
New Orleans and the rest of Louisiana west of the Mississippi were surrendered to the Spanish in 1763. From then until 1783 the East and West Florida were under British control, but as part of the Peace of Paris (1783) the two Florida colonies were regained from Great Britain. Thus, the pioneer parishes of New Orleans and Louisiana were incorporated into the Diocese of Louisiana and the Two Floridas when it was erected on April 25, 1793. The diocese originally encompassed the entire Louisiana Purchase, from the Gulf of Mexico to British North America, as well as the Florida peninsula and the Gulf Coast.
The date of its establishment makes it the second-oldest diocese in the present-day United States: the Diocese of Baltimore was established on November 6, 1789. At the time of its establishment, the territory of the Diocese of Louisiana and the Two Floridas was part of the Archdiocese of San Cristobal de la Habana, based in Havana, Cuba.
The diocese was divided into smaller dioceses several times, and many modern dioceses in the central United States were originally part of the Diocese of Louisiana. As capital of the Louisiana, the city was sold to the United States in 1803. The diocese was renamed the Diocese of New Orleans in 1826, and encompassed what is now Louisiana and Mississippi. New Orleans was elevated to an archdiocese in 1850. As the population of Louisiana grew, the Archdiocese of New Orleans was further subdivided into several additional dioceses.
In its long history, the archdiocese and the city of New Orleans have survived several major disasters, including several citywide fires, a British invasion, the American Civil War, multiple yellow fever epidemics, anti-immigration and anti-Catholicism, the New Orleans Hurricane of 1915, Segregation, Hurricane Betsy, and an occasional financial crisis, not to mention Hurricane Katrina. Each time, the archdiocese rebuilt damaged churches and rendered assistance to the victims of every disaster. More recently, the church has faced an increased demand for churches in the suburbs and a decline in attendance to inner-city parishes. The church has also weathered changes within the Roman Catholic Church, such as the Second Vatican Council, and changing spiritual values throughout the rest of the United States. 
The archdiocese sustained severe damage from Hurricane Katrina and Hurricane Rita. Numerous churches and schools were flooded and battered by hurricane-force winds. In the more heavily flooded neighborhoods, such as St. Bernard Parish, many parish structures were wiped out entirely.
In early 2009, the state of Maine passed a law allowing same-sex civil marriage. In July 2009 the Roman Catholic Archdiocese of New Orleans contributed $2,000 of its money to a referendum campaign to overturn that law. According to Maine's "Commission on Governmental Ethics & Election Practices", the Roman Catholic Diocese of Portland Maine spent over $553,000 to overturn the law. The Archdiocese of New Orleans' $2,000 was part of that $553,000.
The Archdiocese of New Orleans is a culturally diverse community within the diverse city of New Orleans. As a major port, the city has attracted immigrants from around the world. Since French and Spanish Catholics ruled the city, they encouraged enslaved Africans to adopt Christianity. The city has a large population of African American Catholics with deep heritage in the area. Later European immigrants, such as the Irish, Italians, Polish, and German Bavarians have also been a part of the archdiocese throughout its history. In the last quarter of the 20th century, many Vietnamese Catholics from South Vietnam settled in the city. New waves of immigrants from Mexico, Honduras, Nicaragua and Cuba have added to the Catholic congregations.
The best known church in the New Orleans Archdiocese is the historic St. Louis Cathedral fronting the Spanish Plaza de Armas, now Jackson Square, in the French Quarter. This church was originally built in 1718, shortly after the founding of the city. The modest building was destroyed by fire several times before the current structure was built between 1789 and 1794 during the Spanish domination. During renovations to the cathedral between 1849 and 1851, St. Patrick's Church, the second-oldest parish in the city, served as the pro-cathedral of the archdiocese.
The Diocese of Louisiana and the Two Floridas was erected on April 25, 1793; it encompassed the area claimed by Spain as Luisiana, which was all the land draining into the Mississippi River from the west, as well as Spanish territory to the east of the river in modern-day Mississippi, Alabama, and Florida.
In April, 1803, the United States purchased Louisiana from France, which had in 1800 forced Spain to retrocede the territory in the Third Treaty of San Ildefonso. The United States took formal possession of New Orleans on December 20, 1803, and of Upper Louisiana on March 10, 1804. The then-Bishop John Carroll of Baltimore served as apostolic administrator of the diocese from 1805 to 1812; during this period, the diocese became a suffragan of Baltimore. Archbishop Carroll's successor as apostolic administrator would eventually be the diocese's first resident bishop of the 19th century.
In 1823, Joseph Rosati was appointed coadjutor bishop of the diocese. In 1825, the territory of the diocese in what is now Alabama and Florida was transferred to the new Vicariate Apostolic of Alabama and the Floridas, and in 1826, the diocese was renamed, becoming the Diocese of New Orleans. At the same time, the diocese's territory was further reduced by the creation of the Vicariate Apostolic of Mississippi and the Diocese of St. Louis. Bishop Rosati served as the diocese's apostolic administrator from 1826 to 1829; having been appointed bishop of St. Louis two years previously, he resigned the administration of the New Orleans diocese upon the appointment of Bishop de Neckere.
