Lydian is an extinct Indo-European Anatolian language spoken in the region of Lydia, in western Anatolia. The language is attested in graffiti and in coin legends from the late 8th century or the early 7th century to the 3rd century BCE, but well-preserved inscriptions of significant length are so far limited to the 5th century and the 4th century BCE, during the period of Persian domination. Thus, Lydian texts are effectively contemporaneous with those in Lycian.

Cibyra or Kibyra, also referred to as Cibyra Magna, was an Ancient Greek city near the modern town of Gölhisar, in Burdur Province. It lay outside the north-western limits of the ancient province of Lycia and was the chief city of an independent state known as Cibyratis. Since 2016 it has been included in the Tentative list of World Heritage Sites in Turkey.
