Langjökull is, after the Vatnajökull, the second-largest of the glaciers of Iceland (1.021 km2).
It is situated in the west of the Icelandic Interior or Highlands of Iceland and can be seen clearly from Haukadalur.
Its highest peak reaches 1,360 metres (4,460 ft).
The glacier is located at 64°45′N 19°59′W / 64.75°N 19.983°W / 64.75; -19.983.
Two of the bigger highland tracks are leading alongside this glacier: Kaldidalur Highland road and Kjölur Highland road. Kaldidalur is between Langjökull and the volcano Ok in the west, whereas Kjölur lies between Langjökull and Hofsjökull in the east.
In popular culture, the glacier may be best known as the place where pieces of the nuclear-blasted Iron Giant fall in the 1999 animated science fiction film, The Iron Giant, before reassembling themselves.
