Cortébert is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland.

[3] In 1179 the cathedral chapters of Saint-Imier and Moutier-Grandval are listed as major land owners in Cortébert.

[3] In 1530 Biel introduced the Protestant Reformation into the parish of Corgémont which included the village of Cortébert.

[3] During the Early Modern era the village had a successful agricultural and small scale handicraft economy.

A number of houses and workshops were built during the 16th through 19th century, many of which still exist in the center of the village.

In 1865, the watch manufacturer Raiguel Juillard et Cie opened a factory in the village.

In 1938 a pumping station was built in the municipality which provided water to the villages in the Franches-Montagnes plateau.

However, in the 1930s, during the Great Depression, demand for watches plummeted which devastated the municipal economy.

Cortébert Watch struggled to remain in operation until 1962 when it finally closed.

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