The 11th Security Force Assistance Brigade is a brigade of the British Army which is intended to train and assist foreign forces. In 2021, under the Future Army changes, the brigade was redesignated, formerly being the 11th Infantry Brigade & HQ South East.

It was one of the British units sent overseas to France on the outbreak of the First World War in August 1914.

Second World War The 11th Infantry Brigade was originally part of the 4th Infantry Division as it was during the First World War, serving with it during the Battle of France and was evacuated from Dunkirk in late May 1940. It remained with the division in the United Kingdom up until 6 June 1942 when it was reassigned to join 78th Infantry Division (commanded by Vyvyan Evelegh, a previous commander of the brigade) which was being newly formed to take part in Operation Torch, the Allied landings in French North Africa, as part of the British First Army (commanded by Kenneth Anderson, also a previous commander of the brigade).
