Kinsarvik is a village, and former municipality, in the county of Hordaland, Norway.
Kinsarvik was established as a municipality January 1, 1838 (see formann skapsdistrikt). Ullensvang used to be an annex to Kinsarvik - but in 1869 Ullensvang became the main parish, and Kinsarvik became an annex to Ullensvang. (And the municipality then changed the name to Ullensvang.) Kinsarvik and Odda were separated from Ullensvang as municipalities of their own July 1, 1913. Most of Kinsarvik was again merged with Ullensvang January 1, 1964.
The village is today the administrative center of Ullensvang - and it is located at the mouth of the Sørfjorden and the Eidfjorden where it branches from the Hardangerfjord
