The land boundary between the Republic of Albania and the Hellenic Republic (Greece) begins in Lake Prespa at the tripoint with North Macedonia. The land boundary goes in a southwesterly direction for 259 kilometers (161 miles), crossing Lake Prespa and then following a series of watersheds through the Pindus and Gramos mountain ranges before terminating on the coast of Ftelia Bay in the Ionian Sea.

Both Greece and Albania were ruled by the Ottomans for several centuries, eventually gaining independence in 1830 and 1912, respectively. Other major European powers were heavily involved in the delimitation process for Albania’s frontiers following the end of the First Balkan War. Despite the initial boundary delimitation in 1913, work along the border would be stalled due to the onset of World War I. Demarcation work eventually began in 1922 and was finalized four years later.

Today, Albania and Greece maintain generally friendly relations; both are NATO members, and Greece is one of Albania’s largest trade partners and sources of investment. Even so, several issues remain unresolved. Greece’s 1940 state of war law regarding Albania has never been formally repealed by parliament, though Athens considers it inactive. The maritime boundary also remains undelimited: a 2009 agreement was annulled by Albania’s Constitutional Court, and in 2020, the two governments agreed to refer the dispute to the International Court of Justice, although the litigation process has yet to begin.
