Tiger I is the common name of a German heavy tank developed in 1942 and used in World War II. The final official German designation was Panzerkampfwagen VI Tiger Ausf. E, often shortened to Tiger.

It was an answer to the unexpectedly impressive Soviet armour encountered in the initial months of the Axis invasion of the Soviet Union, particularly the T-34 and the KV-1. The Tiger I gave the Wehrmacht its first tank mounting the 88mm gun, in its first armoured fighting vehicle-dedicated version, the (KwK 36).

During the course of the war, the Tiger I saw combat on all German battlefronts. It was usually deployed in independent tank battalions, which proved to be quite formidable.
