(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.
