The Napf is a mountain on the border between the Swiss cantons of Bern and Lucerne. With an altitude of 1,408 meters, it is the summit of the Napfgebiet, the hilly region lying between Bern and Lucerne. It is counted geologically as part of the Swiss plateau, although it is sometimes considered part of the Emmental Alps. The region is bounded by the Emmental to the south-west and the Entlebuch to the east. The region is traversed by the Brünig-Napf-Reuss line.
