Vigra is an island in Giske Municipality in Møre og Romsdal county, Norway. The island is located north of the islands of Valderøya and Giske, west of the mainland of Haram Municipality, and southwest of the island of Lepsøya (in Haram). Vigra has a road connection to the mainland via the Vigra Fixed Link, a series of tunnels and bridges that connect all the islands of Giske Municipality to the city of Ålesund to the south. The island was formerly part of Vigra Municipality.

The largest population centre on the island is the village of Roald on the northern part of the island, on the southeastern edge of Molnesfjellet. Vigra Church is the only church on the island.

Fishing is a popular activity on the island. Ålesund Airport is located on the island of Vigra.
