Innvik is a former municipality in Sogn og Fjordane county in Norway. Innvik is located in the present-day Stryn Municipality, 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.
