Pontenet is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland. It is located in the French-speaking Bernese Jura (Jura Bernois). On 1 January 2015 the former municipalities of Bévilard, Malleray and Pontenet merged to form the new municipality of Valbirse. Pontenet is first mentioned in 1359 as Pontenat. By 1371 Bellelay Abbey was one of the major landholders in the village. In 1515 they granted their lands in the village to Grosjean Girod de Loveresse. During the Early Modern era it was administered by the provost of Moutier-Grandval for the Prince-Bishop of Basel. In 1750 the Birs river flooded and destroyed the village mill, sawmill and bridge over the river.
