The Franz Josef Glacier is a 12-kilometre-long temperate maritime glacier in Westland Tai Poutini National Park on the West Coast of New Zealand's South Island. Together with the Fox Glacier 20 kilometres to the south, and a third glacier, it descends from the Southern Alps to less than 300 metres above sea level. The area surrounding the two glaciers is part of Te Wāhipounamu, a World Heritage Site park. The Waiho River emerges from the glacier terminal of Franz Josef.
