The Sahara Desert covers large parts of the African countries of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia. The desert has an area of over 3.6 million square miles, covering around one-quarter of the continent of Africa.

The Sahara Desert is divided into smaller geographic regions, such as the Libyan Desert, Ténéré desert, western Sahara, Ahaggar Mountains, Tibesti Mountains and Aïr Mountains. The highest elevation in the desert is located in northern Chad’s Tibesti Mountains. The peak is called Emi Koussi, and it rises to an elevation of 11,204 feet above sea level.

The Sahara is bounded on the east by the Red Sea and on the west by the Mediterranean Sea and the Atlantic Ocean. It is bordered on the south by a grassy area known as the Sahel that is part of the Sudan and the Niger River valley. The part of the Sahara known as the Nubian desert is located in the northeast of Sudan, bounded by the Red Sea and the Nile River. Another region of the desert known as the Tanezrouft is located along the border of Mali, Niger and Algeria, just west of the Hoggar mountains. The Eastern Desert is located in parts of Egypt, Sudan and Ethiopia.
