Fiordland National Park (established in 1952) is a vast, remote wilderness and the heart of Te Wāhipounamu - South West New Zealand World Heritage Area in New Zealand's South Island.

Southwest New Zealand is one of the great wilderness areas of the Southern Hemisphere. It is an area where snow-capped mountains, rivers of ice, deep lakes, unbroken forests and tussock grasslands produce a landscape of exceptional beauty. Some of the best examples of animals and plants, which were once found on the ancient super-continent of Gondwana, still exist here.

It is the largest of the 14 national parks in New Zealand, with an area of 12,500 km². The park is administered by the Department of Conservation.
