Mecyberna or Mekyberna (Ancient Greek: Μηκύβερνα) was a town of Chalcidice, ancient Macedonia, which stood at the head of the Toronaic Gulf, which was also called Sinus Mecybernaeus.[1][2] Mecyberna was the port of Olynthus.[3] and lay between that town and Sermyle.[4]
The town was a member of the Delian League, as its name appears in tribute lists from 454/3 to 433/2 BCE.[5] It was taken from the Athenians by the Chalcidic Thracians (420 BCE),[6] and surrendered to Philip II of Macedon before the siege of Olynthus (349 BCE).[7]
The site of Mecyberna is near the modern Molyvopyrgos.[8][9]
