The 151st Infantry Brigade was an infantry brigade of the British Army that saw active service during the Second World War in Belgium and France in 1940, and later in North Africa, Tunisia and Sicily, and later in Normandy in mid-1944 and North-western Europe. The brigade was part of the 50th (Northumbrian) Infantry Division, and for most of its wartime existence consisted of three battalions of the Durham Light Infantry (DLI) the 6th, 8th and 9th.

The 50th (Northumbrian) Infantry Division was an infantry division of the British Army that saw distinguished service in the Second World War. Pre-war, the division was part of the Territorial Army (TA) and the two Ts in the divisional insignia represent the two main rivers of its recruitment area, namely the rivers Tyne, and Tees. The division served in almost all of the major engagements of the European War from 1940 until late 1944 and also served with distinction in North Africa, the Mediterranean and Middle East from mid-1941 to 1943. The 50th Division was one of two British divisions to land in Normandy on D-Day, 6 June 1944, where it landed on Gold Beach. Four men of the division were awarded the Victoria Cross during the war, more than any other division of the British Army during the Second World War.
