The 31st Infantry Brigade was an infantry formation of the British Army, which participated in both the First and the Second World Wars. The brigade was later reformed after the end of the war serving in the British Army of the Rhine until the end of National Service in 1956, which saw the reorganisation of the brigade as the 11th Infantry Brigade.
The 31st Brigade was originally raised in the First World War in 1914, by volunteers from Kitchener's Army. During the First World War, it was assigned to the 10th (Irish) Division and served in the Middle Eastern theatre at Gallipoli, Salonika and Palestine.
