Orkdal Fjord is a branch of the Trondheim Fjord located in Orkland and Skaun municipalities in Trøndelag county, Norway. The Orkdal Fjord starts between Viggja village on the southeast side of the fjord and the village of Geitastrand on the northwest side of the fjord. This is where the Korsfjorden part of the Trondheim Fjord splits into two separate branches; Gaulosen that stretches towards the southeast and the Orkdal Fjord that stretches about 11 kilometres (6.8 mi) towards the southwest to Orkanger and the mouth of the Orkla river at the end of the fjord. For most of its length the fjord is just over 2 kilometres (1.2 mi) wide.
