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.

The North African campaign of the Second World War took place in North Africa from 10 June 1940 to 13 May 1943. It included campaigns fought in the Libyan and Egyptian deserts, in Morocco and Algeria, and in Tunisia. The campaign was fought between the Allies and the Axis Powers. The Allied war effort was dominated by the British Commonwealth and exiles from German-occupied Europe. The United States officially entered the war in December 1941 and began direct military assistance in North Africa on 11 May 1942.
