The 4th Panzer Army () (operating as Panzer Group 4 () from its formation on 15 February 1941 to 1 January 1942, when it was redesignated as a full army) was a German panzer formation during World War II. As a key armoured component of the Wehrmacht, the army took part in the crucial battles of the German-Soviet war of 1941–45, including Operation Barbarossa, the Battle of Moscow, the Battle of Stalingrad, the Battle of Kursk, and the 1943 Battle of Kiev.
