Poliegos (also spelled Polyaigos or Polyegos) is the largest uninhabited island in the Aegean Sea. Located in the Cyclades group, it sits just 2 kilometers (1 nautical mile) southeast of Kimolos and 6.2 kilometers east of Milos.
Its name translates literally to "many goats", derived from the Greek words poly (many) and aiga (goat), as the island's only permanent residents are herds of wild goats.
