Edøy is a former municipality in Møre og Romsdal county, Norway. It is located in the southern part of the present-day Smøla Municipality. The old municipality originally encompassed all the islands surrounding the Edøyfjorden. This included the islands of Smøla, Tustna, Stabblandet, and the many smaller islands between the larger ones. The island of Edøya lies between the two and that was the center of the old municipality. Over time, parts of Edøy were split off to form other municipalities. The Old Edøy Church and later the Edøy Church were the main churches for the municipality.
