Epirus 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.

The Pindus is a mountain range located in Northern Greece and Southern Albania. It is roughly 160 km long, with a maximum elevation of 2,637 metres (8652'). Because it runs along the border of Thessaly and Epirus, the Pindus range is known colloquially as the spine of Greece. The mountain range stretches from near the Greek-Albanian border in southern Albania, entering the Epirus and Macedonia regions in northern Greece down to the north of the Peloponnese. Geologically, it is an extension of the Dinaric Alps, which dominate the western region of the Balkan Peninsula.
