Abdera (τὰ Ἄβδηρα, Strabo; Ἄβδαρα, Ptol.; τὸ Ἄβδηρον, Ephor. ap. Steph. B.) was an ancient seaport town on the south coast of Spain, between Malaca (now Málaga) and Carthago Nova (now Cartagena), in the district inhabited by the Bastuli. It was founded by the Carthaginians as a trading station, and after a period of decline became under the Romans one of the more important towns in the province of Hispania Baetica. It was situated on a hill above the modern Adra.
