Bedouin, derived from the Arabic badawī ( بدوي), a name for a desert-dweller, is a term generally applied to Arab nomadic pastoralist 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 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.
