ADRAR (Berber for "uplands"), the name of various dis tricts of the Sahara, northern Africa. Adrar Sutuf is a hilly re gion in southern Rio de Oro (q.v.). Adrar el Jebli, otherwise Adghagh, a plateau north-east of Timbuktu, is the headquarters of the Awellimiden Tuareg (see TUAREG and SAHARA). Adrar n'Ahnet and Adrar Adhafar are smaller regions in the Ahnet country south of Insalah. Adrar Temur, the best known region of the name, is in the western Sahara, 300m. N. by E. of the Senegal and separated on the north-west from Adrar Sutuf by wide valleys and sand dunes. Adrar is within the French sphere of influence. In general barren, the country, which occupies the centre of a plateau scarped steeply westwards, contains several oases, with a total population of about ro,000. The chief centres of population are Atar, Shingeti, Wadan and Ujeft, Shingeti being the chief commercial centre, whence caravans take to St. Louis gold-dust, ostrich feathers and dates. A considerable trade is also done in salt from the sebkha of Ijil, in the north-west.
Adrar or Adgar is also the name sometimes given to the chief settlement in the oasis of Tuat in the Algerian Sahara.
