Lillium or Lillion (Ancient Greek: Λίλλιον), or Lileon or Lileum (Λιλεόν), or Lilaeus or Lilaios (Λίλαιος), was a commercial town (emporium) on the Black Sea coast of ancient Bithynia, 40 stadia to the east of Dia.[1][2] It is possible that the place may have derived its name from the Lilaeus, which Pliny the Elder mentions among the rivers of Bithynia.[3]
Its site is located east of Akçakoca in Asiatic Turkey.[4][5]
