Storfjorden (or Storfjord) is a 110-kilometre (68 mi) long fjord in the Sunnmøre region of Møre og Romsdal county, Norway. It stretches from the village of Hareid in the west to the villages of Tafjord and Geiranger in the east. The Storfjorden system branches off into several smaller fjords including the famous Geirangerfjord and Tafjorden. At the village of Stranda, the main fjord branches off into the Sunnylvsfjorden-Geirangerfjorden to the west and the Norddalsfjorden-Tafjorden to the east.
The name literally means the "big" or "great" fjord, indicating that this is a long fjord and it is, in fact, the main fjord in this region. Stretching about 110 kilometres (68 mi), Storfjord is the 5th longest fjord in Norway. The Storfjord is a dominant topographical feature in the Sunnmøre region as it cuts the region in two parts that are only connected by ferry. The deepest point in the fjord is 679 metres (2,228 ft) near the village of Dyrkorn in Fjord Municipality.
