Joseph Anthony "Uncle Joe" Ligambi (born August 9, 1939) is an American mobster and former acting boss of the Philadelphia crime family. Ligambi is known among law enforcement circles to have a more "old school" approach, in sharp contrast to boss Joseph Merlino's, flamboyant, high-profile style. Ligambi was credited by the Philadelphia Police Department's Criminal Intelligence Unit with "quietly bringing stability back to the troubled Philadelphia-South Jersey branch of the American Mafia" during the 2000s. The New York Mafia families have been pleased with Ligambi and his approach, as well as his ability to turn the Philadelphia crime family back into a stable group.
