Jökulsárlón is the best known and the largest of a number of glacial lakes in Iceland. It is situated at the south end of the glacier Vatnajökull between Skaftafell National Park and Höfn.

Appearing first only in 1934-1935, the lake grew from 7.9 km² in 1975 to at least 18 km² today because of heavy melting of the Icelandic glaciers. Approaching a depth of 200 m, Jökulsárlón is now probably the second deepest lake in Iceland.

A number of films have had scenes shot at Jökulsárlón, including Beowulf and Grendel, Tomb Raider, Die Another Day (James Bond), Batman Begins and A View to a Kill (James Bond).
