Austfjorden is a
fjord in
Hordaland county,
Norway. The long fjord runs along the border between the municipalities of
Lindås and
Masfjorden. It starts in Lindås and extends to the northwest. The
Masfjorden joins the Austfjorden from the north, and then the Austfjorden empties into the
Fensfjorden before reaching the open sea near
Fedje. The Austfjorden is the innermost arm of the Fensfjorden. The village of
Knarrviki and the
Mongstad industrial area lie on the western shore of the Austfjorden. The village of Myking lies on the western shore of the fjord, near the innermost part of the fjord.
