The AC 37 was a French anti-tank gun of 37mm caliber, developed by the Ateliers de Puteaux. It was principally used in the ouvrages and casemates of the Maginot Line in the late 1930s. It was frequently paired with a model JM twin machine gun.[1]

The AC 37 was superseded by the AC 47 anti-tank gun.
