The 502nd Heavy Panzer Battalion was a German heavy tank battalion during World War II. The battalion was the first unit to receive and field the Tiger I. It fought on the Eastern front. It was one of the most successful German heavy tank battalions, claiming the destruction of 1,400 tanks and 2,000 guns. Otto Carius, one of the best German tank aces, was a member.

A German heavy tank battalion was a battalion-sized World War II tank unit of the German Army (1935–1945), equipped with Tiger I, and later Tiger II, heavy tanks. Originally intended to fight on the offensive during breakthrough operations, the German late-war realities required it to be used in a defensive posture by providing heavy fire support and counter-attacking enemy armored breakthroughs, often organised into ad hoc Kampfgruppen.
