The Western Desert of Egypt is an area of the Sahara that lies west of the river Nile, up to the Libyan border, and south from the Mediterranean Sea to the border with Sudan. It is named in contrast to the Eastern Desert which extends east from the Nile to the Red Sea. The Western Desert is mostly rocky desert, though an area of sandy desert, known as the Great Sand Sea, lies to the west against the Libyan border. The desert covers an area of 680,650 km2 (262,800 sq mi) which is two-thirds of the land area of the country. Its highest elevation is 1,000 m (3,300 ft) in the Gilf Kebir plateau to the far south-west of the country, on the Egypt-Sudan-Libya border. The Western Desert is barren and uninhabited save for a chain of oases which extend in an arc from Siwa, in the north-west, to Kharga in the south. It has been the scene of conflict in modern times, particularly during the Second World War.

The Kharga Oasis lit. 'the outer'; Coptic: (ϯ)ⲟⲩⲁϩ ⲛ̀ϩⲏⲃ (di)wah enhib, "Oasis of Hib", (ϯ)ⲟⲩⲁϩ ⲙ̀ⲯⲟⲓ (di)wah empsoi "Oasis of Psoi") is the southernmost of Egypt's five western oases. It is located in the Western Desert, about 200 km to the west of the Nile valley. "Kharga" or "El Kharga" is also the name of a major town located in the oasis, the capital of New Valley Governorate. The oasis, which was known as the 'Southern Oasis' to the Ancient Egyptians, the 'outer' to the Greeks and Oasis Magna to the Romans, is the largest of the oases in the Libyan desert of Egypt. It is in a depression about 160 km long and from 20 km to 80 km wide. Its population is 67,700 (2012).
