Panzerabwehrkanone (abbreviated as Pak), changed to Panzerjägerkanone in 1941, is the German term for anti-tank gun. In the English-speaking countries, however, Pak refers to the fifteen variants of Wehrmacht's anti-tank gun produced before or during World War II. Of these fifteen, PAW 600 and sPzB 41 do not bear the Pak designation in their names.

Over the six-year course of World War II the armor of the tanks steadily improved, so the size of the projectile had to increase. A larger projectile required a heavier weapon. All of these guns were meant to be towed. The earlier ones were light enough to be moved by hand over short distances, into and out of their firing positions. Some variants were only used on self-propelled guns.
