Innvik is a former municipality in the old Sogn og Fjordane county in Norway. The 511-square-kilometre (197 sq mi) municipality existed from 1838 until 1965. Innvik is located in the present-day Stryn Municipality in Vestland county, encompassing about the western third of the present municipality. Innvik included both sides of the Nordfjorden, from Randabygda in the west to just west of the village of Stryn. It stretched from the border with Hornindal Municipality in the north, through the Oldedalen valley all the way to the Jostedalsbreen glacier in the south.^[1]

The municipality was established as Indvigen formannskapsdistrikt on 1 January 1838. In 1843, the eastern part of the municipality was separated from Innvik to form the new Stryn Municipality, leaving Innvik with 2,675 inhabitants. On 1 October 1922, the Raksgrenda area (between the villages of Loen and Stryn), with 120 inhabitants, was administratively transferred from Innvik to Stryn. During the 1960s, there were many municipal mergers across Norway due to the work of the Schei Committee. On 1 January 1965, Innvik Municipality and neighboring Stryn Municipality were merged back together, creating a much larger municipality named Stryn. Prior to the merger, Innvik municipality had 3,003 inhabitants.^[3]

During its existence, this municipality was governed by a municipal council of directly elected representatives. The mayor was indirectly elected by a vote of the municipal council.^[6]
