The Gambo crime family (pronounced [ɡamˈbo]) is an Italian-American Mafia crime family and one of the "Five Families" that dominate organized crime activities in New York City, United States, within the nationwide criminal phenomenon known as the American Mafia. The group, which went through five bosses between 1910 and 1957, is named after Carlo Gambo, boss of the family at the time of the McClellan hearings in 1963, when the structure of organized crime first gained public attention. The group's operations extend from New York and the eastern seaboard to California. Its illicit activities include labor and construction racketeering, gambling, loansharking, extortion, money laundering, prostitution, fraud, hijacking, and fencing.
