Ionia (; Ancient Greek: /i.ɔː.ní.aː/, "Iōnía" or Ἰωνίη, "Iōníē") was an ancient region on the central part of the western coast of Anatolia in present-day Turkey, the region nearest İzmir, which was historically Smyrna. It consisted of the northernmost territories of the Ionian League of Greek settlements. Never a unified state, it was named after the Ionian tribe who, in the Archaic Period (600–480 BC), settled mainly the shores and islands of the Aegean Sea. Ionian states were identified by tradition and by their use of Eastern Greek.
