Giuseppe Oddi (6 June 1839 - 3 June 1919) was an Italian Roman Catholic professed religious - though not a priest - of the Franciscan Order of Friars Minor.
He felt drawn to religious life after his adolescence and was resolved to become a Franciscan upon seeing the example that Mariano da Roccacasale set.
Upon his profession of vows he assumed the religious name of "Diego from Vallinfreda".Oddi was beatified - alongside Mariano da Roccacasale - on 3 October 1999.
