Fet Church (Norwegian: Fet kyrkje) is a parish church of the Church of Norway in Luster Municipality in Vestland county, Norway. It is located in the village of Fet in the Indre Hafslo area. It is one of the churches for the Fet og Joranger parish which is part of the Sogn prosti (deanery) in the Diocese of Bjørgvin. The white, wooden church was built in a long church design in 1894 by the master builder John Alver using plans drawn up by an unknown architect. The church seats about 220 people.
From the hill where Fet Church is located, it is not long way away to the neighboring Joranger Church. Historians have often wondered why these two churches were built in the Middle Ages so close together. Jon Laberg, the author of the old local history book for Hafslo discussed the reason that Fet and Joranger each have their own churches, even though these farms lie near to each other. Laberg thinks that the owners of these farms could not reach agreement on a common church, so they each built their own church. Today, these two churches belong to the same parish.
