John Sacrimoni, commonly known as Johnny Sack, is a fictional character on the HBO TV series The Sopranos, played by Vince Curatola. He was the longtime underboss and later the boss of the powerful Brooklyn-based New York City Lupertazzi crime family.

Operating out of his Construction Company or Social Club, Johnny Sack was a major player in the New York crime family formerly led by Carmine Lupertazzi. Johnny was Carmine's underboss for many years, handling political payoffs and bid-rigging for the organization. He ultimately became boss after Carmine's death. Johnny was also a friend and contemporary of Tony Soprano. Johnny Sack worked to maintain the peace with the other families, reasoning that peace between all the families led to mutually-increased prosperity. However, Johnny Sack also had a much darker side that sometimes revealed itself during the show. Sacrimoni is a Machiavellian strategist who sowed dissent and suspicion among the ranks of the DiMeo crime family. Johnny Sack's scheming and political manipulation escalated shortly after becoming boss; Sacrimoni shed much of his earlier rationality and aversion to violence as he ruthlessly eliminated rivals and potential threats to his power.

Johnny Sack was very sensitive about his wife, Ginny who was obese. Johnny became violently angry when any remarks were made about Ginny's weight. He once ordered a hit put on Ralph Cifaretto for making one such off-color joke, although he later cooled down and called it off. This saved Ralphie's life, and also, although unknown to Johnny, his own, since Tony had obtained approval from Carmine to hit Johnny to protect the highly valuable Esplanade project to which Ralphie's involvement was key.
