The Mafia (also known as Cosa Nostra or The Commission), is a real-life criminal secret society which first developed in the mid-19th century in Italy. An offshoot emerged on the East Coast of the United States during the late 19th century following waves of immigration. In America, the Mafia often refers to Italian American organized crime in general, rather than just Sicilian American organized crime. Each Mafia family is lead by a Don or Capo Crimine.
The following list shows all mafia families that have appeared or have been mentioned in the Liberty City Survivor series. Note that this does NOT include mafia families from the CAG or CL series, as those gangs are in an entirely different canon of events.
