Fiordland (, "The Pit of Tattooing", and also translated as "the Shadowlands") is a non-administrative geographical region of New Zealand in the south-western corner of the South Island, comprising the western third of Southland. Most of Fiordland is dominated by the steep sides of the snow-capped Southern Alps, deep lakes, and its steep, glacier-carved and now ocean-flooded western valleys. The name "Fiordland" derives from the New Zealand English spelling of the Scandinavian word for steep glacial valleys, "fjord". The geographic area of Fiordland is dominated by, and roughly coterminous with, Fiordland National Park, New Zealand's largest national park.
