Leo of Montefeltro

Saint Leo of Montefeltro (c. 275–366) otherwise Leone of Montefeltro (San Leo di Montefeltro, San Leone di Montefeltro) was the first bishop of Montefeltro from 301. He is traditionally held to have been in origin a stonecutter from Dalmatia. He is venerated as a saint by the Roman Catholic church. His feast day is 1 August.

Some sources claim that Leo was ordained as priest by Gaudentius of Rimini, who ordained Saint Marinus as deacon.
