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

[3] During the Middle Ages the collegiate church of Saint-Imier was the major landholder in Tramelan.

Politically, the villages were part of the seigniory of Erguel under the Prince-Bishop of Basel.

After Napoleon's defeat and the Congress of Vienna, Tramelan was assigned to the Canton of Bern in 1815.

[3] Tramelan's village church was controlled by the Archbishop of Besançon and so formed an enclave in the diocese of Basel.

In 1530, the villages accepted the Protestant Reformation and transferred their allegiance to Basel.

[3] In 1884 a narrow gauge railway connected Tramelan to Tavannes and in 1913 it was extended to Le Noirmont.

The engineering and machining expertise gained from the watch industry allowed Tramelan to diversify into other manufacturing in the 20th century.

During the economic crisis of the 1970s, demand for watches disappeared and many workshops and factories were forced to close, leading to a population decline.

On the following day, 1 January 2010, it joined the newly created Arrondissement administratif Jura bernois.

[7] The blazon of the municipal coat of arms is Gules on a Bend sinister Argent three Linden Leaves issuant from chief of the first.
