Abdera — A settlement in Thrace
Abdera was a major Greek polis on the coast of Thrace. It lay 17 km east-northeast of the mouth of the Nestos River, almost directly opposite the island of Thasos.

Its mythical foundation was attributed to Heracles who founded the city on behalf of his fallen friend Abderus. The historical founding is traced back to a colony from Klazomenai. This historical founding was traditionally dated to 654 BC, which is unverified, although evidence in 7th century BC Greek pottery tends to support it.

The city counted among its citizens the philosophers Democritus, Protagoras and Anaxarchus, historian and philosopher Hecataeus of Abdera, and the lyric poet Anacreon.
