Apollonia (Ancient Greek, Koine Greek: Ἀπολλωνία, ἡ; city-ethnic: Ἀπολλωνιάτης, Apolloniates; Latin: Apollonia; Albanian: Apollonia or Apolonia) was an Ancient Greek trade colony which developed into an independent polis, and later a Roman city in southern Illyria in classical antiquity. It was located on the right bank of the Aoös/Vjosë river, approximately 10 km from the eastern coast of the Adriatic Sea. Its ruins are situated in the county of Fier, close to the village of Pojan, in Albania.
