Pietro Armando Lavini (7 July 1927 – 9 August 2015) was a Roman Catholic Capuchin friar who spent almost his entire life rebuilding, single-handedly, the ruined church of Saint Leonard at Volubrio (Saint Leonard's Hermitage) in a remote mountainous region among Monti Sibillini National Park, Marche, Italy.
The church lies just to the north west of the "Gorges of Hell", a popular naturalistic attraction.
