Gulen is a municipality in the southwestern part of Sogn og Fjordane county, Norway. It is part of the traditional district of Sogn. The administrative center of the municipality is the village of Eivindvik. Other villages in Gulen include Brekke, Byrknes, Dalsøyra, and Dingja.
The municipality of Gulen surrounds the Gulafjorden, which is considered to be the place where Norway's west-coastal Vikings met at the Gulating, a governing body. The area in Gulafjorden called Flolid (just east of the village of Eivindvik) is now a national historic place, where an open air theater and annual summer play commemorates the Vikings who gathered there 1000 years ago to accept Christianity.
Evindvig was established as a municipality on 1 January 1838 (see formannskapsdistrikt). The municipality of 1838 was created to be identical to the Evindvig parish (prestegjeld) that included the three sub-parishes (sokn) of Eivindvik, Brekke, and Husøy. The sub-parish of Brekke (population: 898) was separated from the municipality in 1850 to form a municipality of its own, leaving a total of 3,944 residents in Evindvig.
