Saint Vincent Archabbey is a Benedictine monastery in Westmoreland County, Pennsylvania in the city of Latrobe. A member of the American-Cassinese Congregation, it is the oldest Benedictine monastery in the United States and the largest in the Western Hemisphere. The shrine is dedicated to Saint Vincent de Paul.
The Benedictine monks of Saint Vincent operate and teach at Saint Vincent Basilica Parish, Saint Vincent College, and Saint Vincent Seminary. The monks also provide pastoral care for Catholics in the dioceses of Baltimore, Greensburg, Pittsburgh, Harrisburg, Altoona-Johnstown, and Richmond. The monks also run a military school from the Savannah Priory in Savannah, Georgia (Benedictine Military School). The archabbey also oversees Wimmer Priory in Taiwan, and Saint Benedict Priory in Brazil.
The original abbey structures, including the present church, were designed by the German-American architect J. William Schickel and built between 1891 and 1905. The archabbey church was dedicated by bishop Regis Canevin of Pittsburgh on August 24, 1905 and declared a minor basilica by Pius XII on the same date in 1955. 
Monks from the abbey founded Newark Abbey (Newark, New Jersey) (founded as St Mary's), Saint John's Abbey (Collegeville, Minnesota), Saint Bernard Abbey (Cullman, Alabama), Saint Benedict Abbey (Atchison, Kansas), Saint Mary's Abbey (Morristown, New Jersey), Saint Bede Abbey (Peru, Illinois), Saint Procopius Abbey (Lisle, Illinois), and Mary Help of Christians Abbey (Belmont, North Carolina).
The current archabbot of St. Vincent Archabbey is Martin de Porres Bartel, who was elected by the monastic community on June 23, 2020. He is the twelfth archabbot of Saint Vincent. Bartel succeeded the Rt. Rev. Douglas R. Nowicki.
