Røldal is a former municipality in the southeastern corner of the old Hordaland county, Norway. The 719-square-kilometre (278 sq mi) municipality existed from 1838 until 1964 and it was located in the southeastern part of the present-day Ullensvang Municipality. The administrative centre was the village of Røldal, where the Røldal Stave Church is located. The municipality encompassed the Røldalen valley and some small side valleys, as well as a large area up on the vast Hardangervidda plateau. Historically, Røldal was an important trade and transportation route between Eastern and Western Norway.
