Isfjorden is a branch of the Romsdalsfjorden in Rauma Municipality in Møre og Romsdal county, Norway. The 6.5-kilometre (4.0 mi) long fjord stretches past the town of Åndalsnes and ends at the village of Isfjorden. The Norwegian County Road 64 runs around the whole fjord. The Raumabanen railway line has its terminus at the railway port in the town of Åndalsnes, on the southern coast of the fjord.
During the Battle of Kringen in 1612, Scottish forces sailed into the Isfjorden, landed, and then proceeded to march towards the Romsdalen valley.
