Epirus (/ɪˈpaɪrəs/) is a geographical and historical region in southeastern Europe, now shared between Greece and Albania. It lies between the Pindus Mountains and the Ionian Sea, stretching from the Bay of Vlorë and the Acroceraunian Mountains in the north to the Ambracian Gulf and the ruined Roman city of Nicopolis in the south. It is currently divided between the region of Epirus in northwestern Greece and the counties of Gjirokastër and Vlorë in southern Albania. The largest city in Epirus is Ioannina, seat of the Greek region of Epirus, with Gjirokastër the largest city in the Albanian part of Epirus.
