[3] On 1 January 1965 Avaldsnes was dissolved due to the recommendations of the Schei Committee.

The area of Avaldsnes was divided and merged into the municipalities of Karmøy and Tysvær.

The rest of Avaldsnes located east of the Førresfjorden, consisting of the districts of Førre, Gismarvik, and Stegaberg (population: 994), was merged with Tysvær municipality.

The first element comes from the old male name Ǫgvaldr or Ágvaldr (or the more modern Faroese version Øgvaldur).

[5] The municipal council (Herredsstyre) of Avaldsnes was made up of 21 representatives that were elected to four year terms.
