Heracleium or Herakleion (Ancient Greek: Ἡράκλειον), also known as Lamyron, was a port town of ancient Pontus, on the Black Sea, between Amisus and Polemonium. It was situated on a promontory of the same name (called Herakleios akra (Ἡράκλειος ἄκρα) by Strabo, and Herakleous akron (Ἡρακλέους ἄκρον) by Ptolemy).
