An assault gun is a gun or howitzer mounted on a motor vehicle or armoured chassis, designed for use in the direct fire role in support of infantry when attacking other infantry or fortified positions.

Historically the custom-built fully armored assault guns usually mounted the gun or howitzer in a fully enclosed casemate on a tank chassis. The use of a casemate instead of a turret limited these weapons' field of fire, but provided a simpler construction that was cheaper to build and less prone to mechanical breakdowns. The increased space and reduced weight of the turretless design also allowed mounting a larger weapon and providing heavier frontal armour on any given chassis, and in most cases these turretless vehicles also presented a lower profile as a target for the enemy.
