"Black" Jack Tarr is a fictional character in the Marvel Universe. Jack Tarr is Sir Denis Nayland Smith's aide-de-camp, and is a powerful giant of a man with a gruff manner.

Tarr served with distinction in the British army, and accepted a position with the British Foreign Service after his discharge from the military. Sometime later, he became an agent for the British intelligence agency, MI-6. Eventually, he was assigned to the command of Sir Denis Nayland Smith of Scotland Yard.

While serving with Smith, Tarr came into contact with Shang-Chi and the small band of adventurers fighting a covert war against the criminal mastermind Dr. Fu Manchu. This group includes Lieko Wu and Clive Reston who would become two of his closest friends. Tarr joins them in their fight, confronting Fu Manchu's forces multiple times in many spots around the world. Manchu's forces were legion, including many different cults that sometimes worked together. In one such incident, Tarr and Shang-Chi, cornered by multiple cults, worked together to stun an alligator and throw it at their enemies, gaining them a moment needed to escape.

Tarr is personally targeted by Brynocki, an insane android ruler of a small island. This is part of a plan to gain access to Wu, whom Brynocki had fallen in love with.
