Pelion, also Pellion or Pelium (Greek: Πήλιον, Πέλλιον or Πήλεον, Latin: Pellium) was a fortified settlement of the Dassaretae located on the borderlands between southern Illyria and Macedonia in classical and Roman antiquity. The precise location of Pelion is uncertain and various theories been proposed for the site of the settlement in the Dassaretis region, in Epirus Nova and in Illyricum. It passed different phases of control: the Chaonian tribe of Dexaroi, a coalition of Illyrian tribes, the Macedonian kingdom and finally Rome since at least 198 BCE.
