Jostedalsbreen National Park is a national park in Norway that encompasses the largest glacier on the European mainland, Jostedalsbreen. Jostedalsbreen covers 487 km², and lies in the municipalities of Luster, Balestrand, Jølster and Stryn (in the county of Sogn og Fjordane). The highest peak in the area is Lodalskåpa at 2,083 meters. The glacier's highest point, Brenibba, lies 2,018 meters above sea level while its lowest point is 350 meters above sea level.
The glacier has shrunk in later years, but there are ruins of farms that were overtaken by the glacier in 1750.
There are three museums and also visitorscenters, the Breheimsenteret in Jostedal, Jostedalsbreen nasjonalparksenter in Oppstryn (Stryn) and Norsk bremuseum in Fjærland.
The first element is the name of the old municipality Jostedal, the last element is the finite form of bre m 'glacier'.
