Ålhus is a small village in the municipality of Sunnfjord in Vestland county, Norway.

It is located along the European route E39 highway on the northern side of the lake Jølstravatnet, in a largely agricultural area.

Ålhus is located about 15 kilometres (9.3 mi) west of the villages of Helgheim and Skei and about 8 kilometres (5.0 mi) northeast of the villages of Vassenden and Langhaugane.

Ålhus is the millennium site of Jølster, due to its historical significance.

Audun Hugleiksson erected a stone castle called Audunborg here in the 13th century.
