The Italian invasion of Egypt was an offensive in the Second World War, against British, Commonwealth and Free French in the neutral Kingdom of Egypt. The invasion by the Italian 10th Army ended border skirmishing on the frontier and began the Western Desert Campaign (1940–1943) proper. The Italian strategy was to advance from Libya along the Egyptian coast to seize the Suez Canal. After numerous delays, the scope of the offensive was reduced to an advance as far as Sidi Barrani and the engagement of any British forces in the area.

The Kingdom of Egypt was the legal form of the Egyptian state during the latter period of the Muhammad Ali dynasty's reign, from the United Kingdom's recognition of Egyptian independence in 1922 until the abolition of the monarchy of Egypt and Sudan in 1953 following the Egyptian Revolution of 1952. Until the Anglo-Egyptian treaty of 1936, the Kingdom was only nominally independent, as the United Kingdom retained control of foreign relations, communications, the military, and Sudan. Officially, Sudan was governed as a condominium of the two states; however, in reality, true power in Sudan lay with the United Kingdom. Between 1936 and 1952, the United Kingdom continued to maintain its military presence, and its political advisers, at a reduced level, which resulted in the increase of Egyptian sovereignty and independence.
