Bernardo Provenzano (; 31 January 1933 – 13 July 2016) was a member of the Sicilian Mafia ("Cosa Nostra"). He was suspected of having been the head of the Corleonesi, a Mafia faction from the town of Corleone. He was the de facto "capo di tutti capi" (boss of all bosses) of the entire Sicilian Mafia until his arrest in 2006.
