Thule (Greek: Θούλη, Thoúlē) was a far-northern location in classical European literature and cartography. Though often considered to be an island in antiquity, modern interpretations of what was meant by Thule often identify it as Norway, an identification supported by modern calculations. Other interpretations include Orkney, Shetland, and Scandinavia. In the Late Middle Ages and Renaissance, Thule was often identified as Iceland or Greenland. Another suggested location is Saaremaa in the Baltic Sea. The term ultima Thule in medieval geographies denotes any distant place located beyond the "borders of the known world".
