Saint Gaspar del Bufalo (†1837), also known as Gaspare del Bufalo, was a Roman Catholic priest and the founder of the Missionaries of the Precious Blood. He worked tirelessly to re-evangelize central Italy, especially the Papal States. He was well known for his eloquence in preaching, his devotion to the poor (especially the Santa Galla Hospice in Rome), and his work with the brigands of southern Lazio. He was beatified by St. Pius X in 1904, and canonized by Pope Pius XII on June 12, 1954. His feast day, as indicated in the Roman Martyrology, is on the day of his death, December 28, but has not been included in the General Roman Calendar. Currently Saint Gaspar del Bufalo's feast day is celebrated on October 21.
