Skjervøy is a municipality in Troms county, Norway. The administrative centre of the municipality is the village of Skjervøy on the island of Skjervøya, where most of the inhabitants live. The main industries are fishing and ship building.
The municipality (originally the parish) is named after the small island of Skjervøya (Old Norse: Skerføy), since the first church was built there. The first element is skerf which means "rocky ground" and the last element is øy which means "island". Prior to 1909, the name was written Skjervø.
The coat-of-arms is from modern times. It was granted on 27 March 1987. The arms show the black head of a cormorant on a silver background, partly canting since skarf means cormorant. The cormorant also symbolizes the coastal municipality, which, as the bird, is dependent on fishing for its living. The cormorant is also a common bird in the area.
