Olinto Marella was an Italian Catholic priest who served the Archdiocese of Bologna during the 20th century. Born in Pellestrina in 1882, he was a former classmate of Angelo Roncalli, who later became Pope John XXIII. Marella was recognized for his dedicated pastoral work, particularly his efforts to support the impoverished and homeless. After being declared Venerable in 2013, he was beatified in 2020 following the recognition of a miracle attributed to his intercession.
