ADRA (anc. Abdera), a seaport of southern Spain, in the province of Almeria; at the mouth of the Rio Grande de Adra, and on the Mediterranean Sea. Pop. (1900) 11,188. Adra is the port of shipment for the lead obtained near Berja, 10 m; north-east; but its commercial development is retarded by the lack of a railway. Besides lead, the exports include grapes, sugar and esparto. Fuel is imported, chiefly from the United Kingdom.
