The 2nd Army Corps (2e Corps d'Armée) was first formed before World War I. During World War II it fought in the Campaign for France in 1940 and during the 1944–45 campaigns in southern France, the Vosges Mountains, Alsace, and southwestern Germany. It was active under the First Army for many years after World War II.During the Battle of France, its commander general Jean Bouffet was killed and after the French capitulation, the Corps was dissolved on 26 May 1940.

After Operation Torch, the French troops in North Africa joined the allies, and a new 2nd Army Corps was created in Algeria on 16 August 1943. In November 1943, units of the 2nd Army Corps were used to create the French Expeditionary Corps (1943–44), which fought in Italy.

In September 1944, the 2nd Army Corps landed in the Provence and later liberated Lyon, Autun, Dijon and Chaumont. After having taken over the Vosges and Alsace, the 2nd Army Corps victoriously defended Strasbourg against the German counter-attack in January 1945. In April and May the Corps took part in the German campaign and captured Stuttgart.
