Ellingsøya or Ellingsøy is the northernmost island in Ålesund Municipality in Møre og Romsdal county, Norway.

With an area of 22 square kilometres (8.5 sq mi), Ellingsøya is the second largest island in the municipality after Uksenøya.

The villages of Hoffland, Årset, and Myklebust are all located on the south side of the island.

Ellingsøya used to be accessible from the town of Ålesund only by boat or by road via Skodje Municipality, but the undersea Ellingsøy Tunnel was built in 1987 connecting Ellingsøy to Ålesund (to the south) and the Valderøy Tunnel was also built connecting Ellingsøy to the nearby island of Valderøya in Giske Municipality to the west.

[3][4] Ellingsøya has an association football team, Ellingsøy IL, which currently plays in the 5th division in Norway.
