Gaspar or Gaspare DiGregorio (October 4, 1905 – June 11, 1970) was a New York mobster and a high-ranking member of the Bonanno crime family who was a key figure in the "Banana War". In October 1964, during Joseph Bonanno's two-year absence, Bonanno soldier DiGregorio took advantage of family discontent over Joseph's son Bill Bonanno's role to claim family leadership. The Mafia Commission named DiGregorio as Bonanno family boss, and the DiGregorio revolt led to four years of strife in the Bonanno family, labeled by the media as the "Banana War". This led to a divide in the family between loyalists to Bill and loyalists to DiGregorio.
