Eigerøya is an island in Eigersund municipality in Rogaland county, Norway.

The 19.9-square-kilometre (7.7 sq mi) island lies just off the mainland coast in the town of Egersund.

Eigerøya is separated from the mainland by a narrow 13-kilometre (8.1 mi) long strait.

The Eigerøy Bridge crosses the strait and connects Eigerøya to the mainland.

[1] A naval battle was fought off the island by British and Dutch frigate squadrons at the action of 22 August 1795.
