Aurland is a municipality in the county of Vestland, Norway. It is located on the south side of the Sognefjorden in the traditional district of Sogn. The administrative center is the village of Aurlandsvangen. Other villages include Bakka, Flåm, Undredal, and Gudvangen.

The 1,468-square-kilometre (567 sq mi) municipality is the 60th largest by area out of the 356 municipalities in Norway. Aurland is the 292nd most populous municipality in Norway with a population of 1,781. The municipality's population density is 1.3 inhabitants per square kilometre (3.4/sq mi) and its population has increased by 5.9% over the previous 10-year period.

The name Aurland derives from the Old Norse words aurr (which means "gravel") plus land (which means "land" or "district").

Aurland lies 200 kilometres (120 mi) from the west coast of Norway in the eastern part of Vestland county, along the Aurlandsfjorden and the Nærøyfjorden. These are branches that flow off of the world's longest and deepest fjord, the Sognefjorden.

Aurland is bordered by four municipalities in Vestland county: Lærdal to the north-east and Vik to the west, Voss to the south-west, and Ulvik to the south. It is also bordered by one municipality in Viken county: Hol to the south-east.

Most of the area is composed of fjords and mountains with small populated areas concentrated in the lower river valleys, the largest of which is the Aurlandsdalen. The main village areas include Aurlandsvangen, Gudvangen, Undredal, Flåm, and Vassbygdi.

Wild and beautiful nature dominate the community from the fjords to mountaintops that are 1,200 to 1,800 metres (3,900 to 5,900 ft) above sea level. There are two permanent glaciers in Aurland: Storskavlen and Blåskavlen.

The Aurlandsfjellet mountains separate Aurland from the neighboring municipality to the east, Lærdal. The Lærdal Tunnel, the longest in the world as of 2014, cuts through the mountains connecting the two municipalities. The Gudvanga Tunnel connects the villages of Gudvangen and Undredal in southwestern Aurland.

The West Norwegian Fjords of Geirangefjord and Nærøyfjord were added to UNESCO's World Heritage Site list in 2005. The two fjords are situated 120 kilometres (75 mi) from each other and they are separated by the Jostedalsbreen glacier. The World Heritage Site possesses a unique combination of glacial landforms at the same time as each area is characterised by its own outstanding beauty. The Nærøyfjord areas in this site stretch through the municipalities of Aurland, Lærdal, Vik, and Voss.
