Alfio is an Italian given name of Germanic origin, derived from the elements 'adhel' meaning 'noble' and 'wald' meaning 'rule'. It was brought to Sicily by the Normans and has been used among Sicilian families since then. The name Alfio can also be found in other regions of Italy, though it is most commonly associated with Sicily.
The name Alfio experienced varying popularity over the years, with peaks in the mid-1920s and a steady decline thereafter.
