Helgøya (Norwegian) or Áilu (Northern Sami)[1] is an island (and former fishing village) in Karlsøy Municipality in Troms county, Norway.

It was a large fishing village and the home of the historic Helgøy Church.

No one has permanently lived on Helgøya since 1999 when the post office was closed and regular ferry service was ended.

The island can only be reached when services are celebrated in the church and ferry rides are organized.

The island of Helgøya is now more or less an abandoned village of picturesque wooden houses with a historic church that is used on special occasions.
