Abdera was an ancient seaport town on the south coast of Spain, between Malaca (now Malaga) and New Carthage (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.

Of its coins the most ancient bear the Phoenician inscription abdrt with the head of Heracles (Melkarth) and a tunny-fish; those of Tiberius (who seems to have made the place a colony) show the chief temple of the town with two tunny-fish erect in the form of columns.
