The Førde Fjord (Norwegian: Førdefjorden) is a fjord in Sogn og Fjordane county, Norway. It is the longest of all the fjords in the traditional district of Sunnfjord. It passes through the municipalities of Førde, Naustdal, Askvoll, and Flora. The fjord begins at the town of Førde, at the estuary of the river Jølstra, which comes from the lake Jølstravatn. The water then travels west towards the town of Florø where the 36-kilometre (22 mi) long fjord splits into the Brufjorden and Stavfjorden before reaching the sea. The island of Svanøya lies just outside of the mouth of the fjord.
