Mont-Tramelan (French pronunciation: [mɔ̃ tʁamlɑ̃]) is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland.

Around 1570 the Prince-Bishop of Basel allowed Anabaptist refugees from the Emmental to settle in the seigniory of Erguel, including in the area that would become Mont-Tramelan.

The farms in the area were part of the parish of Tramelan, which adopted the Reformed faith in 1530.

It remained under French authority until 1814 and in following year became part of the Canton of Bern.
