Bru is a former municipality in the old Sogn og Fjordane county, Norway. The 382-square-kilometre (147 sq mi) municipality existed from 1923 until 1964 and it included several islands including Svanøya, Askrova, and Stavøya as well as parts of the mainland including the Solheimsdalen valley, east of the village of Norddalsfjord. It is now part of the present-day Kinn Municipality which is in Vestland county in the traditional district of Sunnfjord. The administrative center of Bru was the village of Stavang.

Sogn og Fjordane was, up to 1 January 2020, a county in western Norway, when it was merged to become part of Vestland county. Bordering previous counties Møre og Romsdal, Oppland, Buskerud, and Hordaland, the county administration was in the village of Hermansverk in Leikanger municipality. The largest town in the county was Førde.
