San Pietro in Valle is a medieval abbey in the comune of Ferentillo in Umbria.
The Romanesque church houses some particularly fine Roman sarcophagi; the walls of the nave are decorated with a large cycle of good Romanesque frescoes. The monastery buildings are private property and today house a luxury hotel.
