Bergsdalen is a river valley in Vaksdal Municipality in Vestland county, Norway.

The 16-kilometre (9.9 mi) long valley begins at the lake Hamlagrøvatnet on the border of the municipalities of Vaksdal, Voss, and Kvam.

This valley was historically part of the main route between the city of Bergen and Voss, until the European route E16 highway was built to the north of the valley.

The Bergsdalen valley now is home to a significant number of mountain cabins and there is especially a lot of tourist activity in the winter.
