Måsøya (Norwegian) or Muosáidsuolu (Northern Sami)[1] is an island in Måsøy Municipality in Finnmark county, Norway.

The island is only accessible by boat, and there is regular ferry service from Havøysund.

It is located on the southern part of the island on an isthmus between two small fjords.

Historically, the village was the administrative centre of the municipality and it is where Måsøy Church is located.
