Jagdpanzer (JgPz) is the name given in German to an armored, tracked tank destroyer, although it may also be used for other kinds of self-propelled guns. Translated from the German, Jagdpanzer means "hunting tank".

A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities.
