The 8.8cm Flak 18/36/37/41 is a German 88mm anti-aircraft and anti-tank gun, developed in the 1930s. It was widely used by Germany during World War II and is one of the most recognized German weapons of that conflict. The development of the original model led to a wide variety of weapons.

The name applies to a series of related guns, the first officially the 8.8cm Flak 18, the improved 8.8cm Flak 36 and later the 8.8cm Flak 37. Flak is a combination of the German Flugabwehrkanone (also known as Fliegerabwehrkanone) meaning 'aircraft defense gun', the weapon's original purpose. In English, "flak" became a general term for anti-aircraft fire on the ground. In informal use, the guns were commonly known as the Acht-acht ("eight-eight") by Germans and the "eighty-eight" by the Allies.
