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.

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.

[3] Porro was beatified in 1737 after Pope Clement XIII confirmed that there was an enduring and local 'cultus' - or popular veneration - to the late priest.

[2] The death of his father in 1468 prompted him to enter the Servite Order around this time while becoming a professed member on 20 December 1470.

[1][2] Towards the end of 1488 the unwell Porro went to the Basilica of the Annunciation in Florence and after his recuperation spent a few months as a convent prior in Chianti.
