The municipality of Ulstein was established as a municipality on 1 January 1838. It originally included most of the island of Hareidlandet and the Vartdal area southeast of the Vartdalsfjorden on the mainland. On 1 January 1895, the area southeast of the Vartdalsfjorden was separated from Ulstein Municipality to become the new municipality of Vartdalsstranden. This left Ulstein with 2,996 residents. Then on 1 January 1917, the eastern half of the island of Hareidlandet was separated from Ulstein to form the new Hareid Municipality. This left 2,336 residents in Ulstein. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1964, the island of Eika, the village of Eiksund, and the surrounding area were transferred from Herøy Municipality to Ulstein Municipality.
Name
The municipality is named after the old Ulstein farm, since the first Ulstein Church was built there. The first element is ulfr which means "wolf" and the last element is steinn which means "stone mountain". Before 1879, the name was written Ulfsten or Ulfsteen, then between 1879-1888 it was spelled Ulvsten, and since 1889, it has been spelled Ulstein.
Coat of arms
The coat of arms was granted on 30 May 1986. The arms show a bar described as wolf-toothed, which makes the bar a canting since ulv means wolf and the municipality is named after the Ulva river. The blue colour represents the sea and the gold represents wheat.
There are several villages throughout the municipality. The largest is the town of Ulsteinvik and others include the villages of Haddal, Flø, Eiksund, Ringstad, Sundgot, Hasund, Varleite. The island of Dimnøya is just outside Ulsteinvik, and there are many residents there. There are also several small populated islands surrounding the main island of Hareidlandet: Eika, Vattøya, and Hatløya.
