Valsøyfjorden is a fjord in Heim Municipality in Trøndelag county, Norway. It is a 10-kilometre (6.2 mi) fjord arm off of the Arasvikfjord and it runs south past the island of Valsøya. The villages along the fjord include Engan, Hjellnes, and Valsøybotnen. The Valsøy Bridge is part of European route E39 and it was built in 1993 to cross over mouth of the fjord so travelers did not have to drive all the way around the fjord. The village in Valsøyfjord lies on the west side of the mouth of the fjord.
