Bedouin, derived from the Arabic badawi بدوي, a generic name for a desert-dweller, is a term generally applied to Arab nomadic groups, who are found throughout most of the desert belt extending from the Atlantic coast of the Sahara via the Western Desert, Sinai, and Negev to the eastern coast of the Arabian desert. It is occasionally used to refer to non-Arab groups as well, notably the Beja of the African coast of the Red Sea.
