The 69th Infantry Brigade was an infantry brigade of the British Army in the Second World War. It was a second-line Territorial Army formation, and fought in the Battle of France with the 23rd (Northumbrian) Division. The brigade was later part of the 50th (Northumbrian) Infantry Division. It went on to fight in the North African campaign, the Allied invasion of Sicily, the Normandy landings and the North West Europe campaign.

The 23rd (Northumbrian) Division was an infantry division of the British Army, which fought briefly in the Battle of France during the Second World War. In March 1939, after the re-emergence of Germany as a European power and its occupation of Czechoslovakia, the British Army increased the number of divisions within the Territorial Army by duplicating existing units. The 23rd (Northumbrian) Division was formed in October 1939, as a second-line duplicate of the 50th (Northumbrian) Motor Division. It was made up of two brigades, unlike regular infantry divisions that were composed of three, with battalions hailing from the north of England.
