Algeria, officially the People's Democratic Republic of Algeria, is a country in the Maghreb region of North Africa. It is bordered to the northeast by Tunisia; to the east by Libya; to the southeast by Niger; to the southwest by Mali, Mauritania, and Western Sahara; to the west by Morocco; and to the north by the Mediterranean Sea.

With a population of 44 million, Algeria is the tenth-most populous country in Africa, and the 32nd-most populous country in the world. The capital and largest city is Algiers, located in the far north on the Mediterranean coast.
