Vatnajökull, also known as the Vatna Glacier, is the largest and most voluminous ice cap in Iceland, and one of the largest in area in Europe. It is the second largest glacier in area after Austfonna on Svalbard in Norway. It is located in the south-east of the island, covering more than 8 percent of the country.
With an area of 8,100 km², Vatnajökull is the largest ice cap in Europe by volume (3,100 km³) and the second-largest (after Austfonna on Nordaustlandet, Svalbard, Norway) in area (not counting the still larger Severny Island ice cap of Novaya Zemlya, Russia, which may be regarded as located in the extreme northeast of Europe). On 7 June 2008, it became a part of the Vatnajökull National Park.
