Chaonia or Chaon (Ancient Greek: Χαονία or Χάων) was the name of the northwestern part of Epirus, the homeland of the Epirote Greek tribe of the Chaonians. It was one of the three main areas of ethnic division of Epirus, the other being Molossia and Thesprotia.

Chaonia traditionally stretched between the Thyamis river in the south and the Akrokeraunian range in the north, between present-day Greece and Albania. Its main town was called Phoenice. In Virgil's Aeneid, Chaon was the eponymous ancestor of the Chaonians.
