Operation Perch was a British offensive of the Second World War which took place from 7 to 14 June 1944, during the early stages of the Battle of Normandy. The operation was intended to encircle and seize the German occupied city of Caen, which was a D-Day objective for the British 3rd Infantry Division in the early phases of Operation Overlord. Operation Perch was to begin immediately after the British beach landings with an advance to the south-east of Caen by XXX Corps. Three days after the invasion the city was still in German hands and the operation was amended. The operation was expanded to include I Corps for a pincer attack on Caen.

XXX Corps was a corps of the British Army during the Second World War. The corps was formed in the Western Desert in September 1941. It provided extensive service in the North African Campaign and many of its units were in action at the Second Battle of El Alamein in late 1942. It then took part in the Tunisia Campaign and formed the left flank during the Allied invasion of Sicily in 1943.
