Fensfjorden is a fjord on the border of Hordaland and Sogn og Fjordane counties in Norway. The long fjord begins in the North Sea at Holmengrå Lighthouse and flows to the southeast through the municipalities of Austrheim, Gulen, Lindås, and Masfjorden. The fjord ends on the Masfjorden-Lindås border where it splits into two fjords: Masfjorden (which flows to the northeast into Masfjorden municipality) and Austfjorden (which flows southeast into Lindås municipality).
