The Bastarnae (Latin variants: Bastarni, or Basternae; Ancient Greek: Βαστάρναι or Βαστέρναι) were an ancient people who between 200 BC and 300 AD inhabited the region between the Carpathian mountains and the river Dnieper, to the north and east of ancient Dacia. The Peucini, denoted a branch of the Bastarnae by Greco-Roman writers, occupied the region north of the Danube delta.
