Glaciers in mainland Norway have importance for hydropower production, climate research and tourism, but are also a source of natural hazards. Glacier influence on river discharge and hydropower production has resulted in an extensive glacier measurement record.

1.  Jostedalsbreen (474 km2)
2.  Vestre Svartisen (219 km2)
3.  Søndre Folgefonna (164 km2)
4.  Østre Svartisen (148 km2)
5.  Blåmannsisen (87 km2)
6.  Hardangerjøkulen (71km2)
7.  Okstindbreen (54 km2)
8.  Myklebustbreen (48 km2)
