The AC 47 was a French anti-tank gun of 47mm caliber. It was principally used in the ouvrages and casemates of the Maginot Line in the late 1930s; another version was created for naval use.

The AC 47 was principally used as a defensive weapon, since its portability was intentionally limited to prevent the weapon from being turned on defending troops if a fortification was captured.
