Major General Douglas Alexander Henry Graham, was a senior British Army officer who fought with distinction in both world wars. He is most notable during the Second World War for commanding the 153rd Brigade of the 51st (Highland) Division in North Africa from 1942 to 1943, later being the General Officer Commanding (GOC) of the 56th (London) Infantry Division during the Salerno landings in Italy in September 1943 and the 50th (Northumbrian) Infantry Division during the Normandy landings in France in June 1944.

153rd Infantry Brigade was a formation of Britain's Territorial Force/Territorial Army that was part of 51st (Highland) Division in both World Wars. From its origins in the 19th Century Volunteer Force it was based in Aberdeen and was composed of Highland battalions. It served on the Western Front in World War I, and after it was captured at Saint-Valery-en-Caux early in World War II it was reformed from its 2nd Line and saw action in North Africa, Sicily and North West Europe. It continued serving postwar until the reduction of the Territorial Army in the 1960s.
