Bolsøya is an island in Molde Municipality in Møre og Romsdal county, Norway.

The 5.2-square-kilometre (2.0 sq mi) island lies in the Romsdalsfjorden at the entrance to the Fannefjorden.

The island is connected to the mainland by the Bolsøy Bridge and to the town of Molde by the Fannefjord Tunnel, both on County Road 64.

The island is unique due to its 6-kilometre-long (3.7 mi) finger-shaped peninsula that is only 400 metres (1,300 ft) wide at its widest.
