The surname Mastroianni was first found in Italy. Mastroianni is mentioned in early documents all over Italy, as the surname Mastro, or Maestro, is only part of other Italian names. It was not until they emigrated, that families bearing names such as Mastr-antonio, Mastrogiovanni, and others, had their names shortened to Mastroianni. This was especially prevalent in North American immigration.
