The 13th Army (Russian: 13-я армия, romanized: 13-ya armiya, Ukrainian: 13-та армія, romanized: 13-ta armiya) was a name given to several field armies of the Soviet Union's Red Army. Later armies existed until the 1990s, and the army survived as part of the Ukrainian Ground Forces for some years.

The 13th Army was created again at the end of December 1939 as a separate 13th Army in the course of the Soviet advance into the Karelian Isthmus when the 7th Army was split into two, and also renamed separate, after being substantially reinforced.^[1] As part of the 1940 February Vyborg offensive they were coordinated by the North Western Front in Leningrad, both armies were able to breach either first or second defensive positions in the Mannerheim Line, but were unable to breach the main position. The separate 13th Army was allocated three of the eight rifle corps assigned to the operation.^[2]

The 13th Army (1st formation) headquarters was formed in May 1941 in the Western Special Military District, starting on 5 May in Mogilev in accordance with the decision of Central Committee of the Communist Party and Sovnarkom of the USSR No.1113-460cc. dated 23 April 1941.^[3] It was intended to comprised 21st, 2nd, and 44th Rifle Corps.^[4] In the beginning of June Lieutenant General Pyotr Filatov arrived to take command. From the beginning of Operation Barbarossa the Army included the 21st Rifle Corps, 50th Rifle Division, the 8th Anti-Tank Artillery Brigade and a number of other separate units. From the end of June 1941 the Army conducted defensive operations in the Minsk Fortified Region, on the Borisov direction and on the Dnieper river. The formation conducted operations as part of the Soviet Western Front and the Soviet Central Front. Parts of the Army held up the Wehrmacht advance for almost three weeks near Mogilyev. The 172nd Rifle Division under Major General Mikhail Romanov especially distinguished itself in the combat. Parts of the Army participated in the Battle of Smolensk from 10 July to 10 September 1941. During September and October 1941 the Army was operating as part of the Bryansk Front and included the 6th Rifle Division.

The Army fought as part of the Central Front in the Battle of Kursk in July 1943 under General N.P. Pukhov, numbering four corps with twelve rifle divisions (including the 75th Guards Rifle Division). The Army finished its war service in Germany within the 1st Ukrainian Front in 1945, consisting of the 24th Rifle Corps (117th Guards Rifle Division, 280th Rifle Division, 395th Rifle Division), 27th Rifle Corps (6th Guards Rifle Division and 121st Guards Rifle Division), 102nd Rifle Corps (147th Rifle Division and 172nd Rifle Divisions, which took part in the Battle of Halbe), 17th Artillery Division, and many other smaller artillery and other formations.^[5]

The Army was located for the entire postwar period in the Lviv and Carpathian Military Districts, initially comprising three Rifle Corps with a total of nine rifle divisions. From 1947 to 1949 it was commanded by General Issa Pliyev who was a renowned commander of several Cavalry mechanized groups during the war. It was for much of this period headquartered at Rovno. Almost all its divisions were Guards formations: the 17th, 51st, 97th (the former 40th, 15th, and 97th Rifle Divisions). Only the 24th (subsequently resubordinated to Military District control) and the 161st Rifle Division were not Guards, but both were renowned combat formations.
