Anthony Joseph Giacalone, known as Tony Giacalone and by the nickname Tony Jack (January 2, 1919 – February 23, 2001) was an American organized crime figure in Detroit, serving as a capo in the Detroit Partnership. He came to public notice during the 1970s during investigations into the disappearance of Jimmy Hoffa, as he was one of two Mafia members – the other being Anthony Provenzano – that Hoffa was to meet the day he disappeared. Giacalone was later jailed for ten years in 1976 for income tax fraud.
Giacalone was born on January 2, 1919.
Early involvement in crime 
Dan E. Moldea, author of The Hoffa Wars, detailed Giacalone's early career in the Detroit Mafia "running errands for bookmakers" before becoming an enforcer for crime boss Joseph Zerilli. He earned a reputation as a "tough guy and a natty dresser" with a stare of "cold intensity" according to Mike Wendland.
Giacalone died on February 23, 2001, aged 82. He had been admitted to St. John's Hospital and Medical Center in Detroit for heart failure and complications arising from kidney disease.
