The College of Sant'Anselmo (Italian: Collegio Sant'Anselmo) is an international Benedictine college founded by Pope Leo XIII in 1887 and located in Rome, Italy. Situated on the Aventine Hill, it is one of four Benedictine institutions that occupy the complex known as "Sant'Anselmo all'Aventino" which serves as the Primatial Abbey (Italian: Badia Sant'Anselmo) of the Benedictine Confederation. As an ecclesiastical residential college in the Roman College tradition, it serves as both a house of formation for Benedictines, but also as a residence for over one hundred monks from around forty countries, religious, diocesan priests, and lay people. It offers a monastic environment for those who study at the onsite Pontifical Athenaeum of Saint Anselm or at other Roman pontifical universities.
