Giovannangelo Porro (1451 - 23 October 1505) was an Italian Roman Catholic priest and hermit who hailed from the Milanese region and was a professed member of the Servites. Porro was born to nobles and became a priest after the death of his father. He remained a hermit in convents in places such as Florence and Milan where he dedicated his life to inward meditation and self-mortification until his death. Charles Borromeo was healed as a child due to Porro's intercession and carried with him a foot bone fragment from Porro's incorrupt remains.
