The 4th Army was a Soviet field army of World War II that served on the Eastern front of World War II and in the Caucasus during the Cold War. It was disbanded after the fall of the Soviet Union, with its divisions being withdrawn to Russia and disbanded.

The Fourth Army was created in August 1939 in the Belorussian Special Military District from the Bobruisk Army Group as an independent army. In September 1939, the Fourth Army took part in the Soviet invasion of Poland commanded by the future Marshal of Soviet Union V.I. Chuykov, the defender of Stalingrad. Its order of battle in that operation is listed here. Elements of the army, apparently 4th Battalion, 29th Light Tank Brigade, took part in the German–Soviet military parade in Brest-Litovsk on September 22, 1939.

When the German invasion of the Soviet Union commenced on 22 June 1941, the Army was part of the Western Front and had the 28th Rifle Corps (6th Rifle Division and 42nd Rifle Division), 14th Mechanised Corps, and 49th and 75th Rifle Divisions, as well as the 62nd Fortified Region. General Colonel Pavlov, Commander of the Western Front, had decided to redeploy some of 4th Army’s troops early in 1941, and John Erickson wrote that 12th Rifle Division was accordingly moved into Brest, and HQ 14th Mechanised Corps to Kobrin, which in Erickson’s words, ‘deprived 4th Army simultaneously of its reserve and its second echelon.’
