The Charioteer Tank, or FV4101 Tank, Medium Gun, Charioteer was a post-war British armoured fighting vehicle. The vehicle was produced in the 1950s to up-gun units of the Royal Armoured Corps continuing to use the Cromwell tank during the early phases of the Cold War. The vehicle itself was a modified Cromwell with a more powerful gun installed in a relatively lightly armoured two-man turret.

Charioteer saw limited use with the British army, but saw more extensive use with overseas users in Europe and the Middle East. Charioteers saw action in conflicts in the Middle-East.
