Antonio Pietro Cortinovis (7 November 1885 - 10 April 1984) - in religious Cecilio Maria da Costa Serina - was an Italian Roman Catholic professed religious from the Order of Friars Minor Capuchin. He had set his heart on entering the religious life despite his initial reluctance due to him pondering on his unworthiness. This belief manifested in his childhood which motivated him to decide against entering the priesthood. But his religious formation in the order was pushed back due to World War I and he was unable to make his solemn religious profession until the war had concluded.
