Vatnajökull (Icelandic pronunciation: [ˈvahtnaˌjœːkʏtl̥] ⓘ, literally "Glacier of Lakes"; sometimes translated as Vatna Glacier in English) is the largest and most voluminous ice cap in Iceland, and the second largest in area in Europe after the Severny Island ice cap of Novaya Zemlya.

[5] Iceland's highest peak, Hvannadalshnúkur (2,109.6 m or 6,921 ft 3 in), as part of the Öræfajökull, is in the southern periphery of Vatnajökull, near Skaftafell.

Hrútsfjallstindar is a series of Icelandic peaks rising from Vatnajökull between Svínafellsjökull and Skaftafellsjökull, in its southern part.

[9] An Icelandic older name for Vatnajökull was Klofajökull [ˈkʰlɔːvaˌjœːkʏtl̥] (Cleft Glacier, due to cuts into the ice several of which can be presumed to be liable for the name), which is known from eighteenth-century sources such as the writings of Eggert Ólafsson and Bjarni Pálsson.

[13] Westlife's official music video for their twenty-fifth single top 10 and #2 UK hit in 2009 "What About Now" is the last film of Vatnajökull Glacier before the subsequent volcanic eruption.

[14] In November 2011, the glacier was used as a shooting location for the second season of the HBO fantasy TV series Game of Thrones.
