The Abbey of Sant'Antimo, Italian: Abbazia di Sant'Antimo, is a former Benedictine monastery in the comune of Montalcino, Tuscany, central Italy. It is approximately 10 km from Montalcino about 9 km from the Via Francigena, the pilgrim route to Rome. Disused for many years, the abbey has since 1992 been in use by a small community of Premonstratensian Canons Regular.
