Founded 1855, the American-Cassinese Congregation is a Catholic association of Benedictine monasteries in the Benedictine Confederation.
The Congregation consists of 20 independent monasteries with houses or dependencies in 16 of the United States, Puerto Rico, and in six other countries on three continents.
Abbot Boniface Wimmer OSB, founder of Saint Vincent Archabbey in Latrobe, Pennsylvania, created the Congregation. Pope Pius IX erected it as a monastic congregation under the patronage of the Holy Guardian Angels.
The monasteries of the Congregation follow the Rule of Saint Benedict of Nursia (480-547).
