Egypt, officially the Arab Republic of Egypt (Jumhuriyat Misr al-Arabiyah in Arabic), country in northeastern Africa and southwestern Asia. Most of the country lies in Africa, but the easternmost portion of Egypt, the Sinai Peninsula, is usually considered part of Asia; it forms the only land bridge between the two continents. Most of Egypt’s terrain is desert, divided into two unequal parts by the Nile River. The valley and delta of the Nile are the main centers of habitation.
Although present-day Egypt is an overwhelmingly Arabic-speaking and Islamic country, it retains important aspects of its past Christian, Greco-Roman, and ancient indigenous heritage. Egypt is an important political and cultural center for the entire Arab world.
