Boniface of Valperga was a thirteenth-century Roman Catholic bishop of Aosta who was born in Turin. A member of a noble family from the Canavese region, he received his education from his uncle, the Bishop of Turin. He initially joined the Benedictine order at the abbey of Fruttuaria before moving to the Augustinian Collegiate church of Saint Ursus. After serving as Prior, he was appointed to the bishopric in 1219, a position he maintained until his death in 1243.
