Anthony Joseph Giacalone (January 9, 1919 – February 23, 2001), also known as Tony Jack, was an American organized crime figure in Detroit, serving as a capo in the Detroit Partnership.
He came to public notice during the 1970s investigations into the disappearance of Jimmy Hoffa, as he was one of two Mafia members – the other being Anthony Provenzano – that Hoffa had arranged to meet on the day he disappeared.
Giacalone was later jailed for ten years in 1976 for income tax fraud.
