Termera (Ancient Greek: τὰ Τέρμερα), also known as Termerum or Termeron (Τέρμερον), was a maritime town of ancient Caria on the south coast of the peninsula of Halicarnassus, near Cape Termerium.[1][2][3]Stephanus of Byzantium erroneously assigns the town to Lycia.[4] It was a polis (city-state) and a member of the Delian League.[5] Under the Romans this Dorian town was a free city. According to the Suda the place gave rise to the proverbial expression Τερμέρια κακά, it being used as a prison by the rulers of Caria.[6] In Greek mythology, it was founded by Termerus, after whom it was named.
