Tommaso Bellacci (1370 - 31 October 1447) was an Italian member of the Third Order of Saint Francis. Bellacci was a butcher and became a religious after turning his life around from one of sin to one of penance and servitude to God. Bellacci travelled across the Middle East and the Italian peninsula to preach and administer to people despite not being an ordained priest. His beatification was celebrated in 1771.
