Army Group B (German: Heeresgruppe B) was the name of four distinct German army group commands that saw action during World War II.

The first Army Group B was created on 12 October 1939 (from the former Army Group North) and fought in the Battle of France on the northern flank. It was responsible for a part of the German invasion of Belgium and the majority of the German invasion of the Netherlands. In the later stage of that campaign ("Case Red"), it again advanced on the German right flank towards the Somme river, the city of Paris and the Franco-Spanish border. After 16 August 1940, it was deployed to East Prussia and to the General Government in German-occupied Poland. When Operation Barbarossa began on 22 June 1941, Army Group B was renamed on the same day to become "Army Group Center".

The second Army Group B came into existence on 9 July 1942, when Army Group South was split into two army groups, named Army Group A and Army Group B. Army Group B was responsible for the northern flank of the German 1942 summer offensive towards the Volga river and the Caucasian oilfields. Its most famous operational target was the major city of Stalingrad. Beginning on 21 November 1942, the army group had its lines repeatedly pierced by Red Army counterattacks ("Operation Uranus"), developing into the encirclement crisis during the Battle of Stalingrad that ended with the destruction of the German 6th Army trapped in the city. Army Group B was organizationally weakened by the creation of Army Group Don, which was inserted into the line between Army Groups A and B to alleviate the crisis at Stalingrad. After additional pressure was applied to the army group by the Soviet Voronezh–Kharkov offensive (January – March 1943), the army group was dissolved on 9 February 1943 and its subordinate formations divided between Army Group Center and the newly-reestablished Army Group South (formerly Army Group Don).

The third Army Group B was formed on 19 July 1943 using former Army Group B personnel as well as Task Force Rommel (German: Arbeitsstab Rommel) and deployed to northern Italy. Here, the staff was used on 26 November 1943 to create OB Südwest ("Army Group C").

On the same day, 26 November 1943, another Army Group B command was created at the coast of the English Channel in German-occupied France. After the Allied Normandy landings in June 1944, Army Group B initially commanded the northern wing of the new Western Front. After Army Group H was created in the German-occupied Netherlands in November 1944, Army Group B instead took the center of the Western Front, located between Army Group H to the north and Army Group G to the south. It is notable on the Western Front as the army group to oversee the German Ardennes Offensive ("Battle of the Bulge"). Eventually, Army Group B surrendered on 17 April 1945 in the Ruhr pocket.
