The Bastarnae (Latin variants: Bastarni or Basternae; Βαστάρναι or Βαστέρναι), sometimes called the Peuci or Peucini (Πευκῖνοι), were an ancient people who between 200 BC and 300 AD inhabited areas north of the Roman frontier on the Lower Danube. The Bastarnae lived in the region between the Carpathian Mountains and the river Dnieper, to the north and east of ancient Dacia. The Peucini were a subtribe who occupied the region north of the Danube Delta. Their name was sometimes used for the Bastarnae as a whole.
