Frei is a former municipality in Møre og Romsdal county, Norway. It is located in the present-day Kristiansund Municipality between the Kvernesfjorden and Freifjorden. The municipality existed from 1838 until 2008 and upon its dissolution, it included the island of Frei and the smaller surrounding islands, totaling about 65 square kilometres (25 sq mi).

The administrative centre of the municipality was the village of Rensvik, the largest village on the island, located on the northern end of the island. Other main villages that were in Frei Municipality include the village of Nedre Frei, located on the southern end of the island and the village of Kvalvåg, located on the eastern side of the island. The main church for the municipality was Frei Church, located in the village of Nedre Frei.

The municipality was named after the island of Frei (Old Norse: Freiðr). The meaning of the name is unknown, but is maybe derived from fríðr which means "good" or "beautiful". Until 1889, the name was written Fredø.

The municipality of Fredø was established on 1 January 1838 (see formannskapsdistrikt). On 1 January 1882, a small part of Fredø (population: 40) was merged into Øre Municipality to the south. On 1 September 1893, an area of Frei (population: 231) was merged into the new Gjemnes Municipality. On 1 January 1964, the northern part of the island of Frei was transferred from Bremsnes Municipality to Frei, also the part of Frei on the island of Aspøya (population: 147) was transferred to Tingvoll Municipality. On 1 January 2008, Frei Municipality ceased to exist when it was merged into the neighboring Kristiansund Municipality to the north.
