Lamboing (French pronunciation: [lɑ̃bwɛ̃]) is a municipality in the Jura bernois administrative district in the canton of Bern in Switzerland, located in the French-speaking Bernese Jura (Jura Bernois).

The proposed merger of the municipalities of Diesse, Lamboing, Nods and Prêles into the new municipality of Le Plateau de Diesse was rejected by voters. However, on 1 January 2014 the former municipalities of Lamboing, Diesse and Prêles merged into the new municipality of Plateau de Diesse.

Lamboing is first mentioned in 1179 as Lamboens though this document is thought to be a forgery from the late 12th Century. In 1235 it was mentioned as Lamboens.

The noble de Lamboing family was first mentioned in a document from 1255. But very little is known about this family. In 1423 the de Vaumarcus family were given the village as a fief, which they held until 1509. In that year the village was acquired by the Prince-Bishopric of Basel who ruled over the village for almost three centuries. After the 1798 French invasion, Lamboing became part of the French Département of Mont-Terrible. Three years later, in 1800 it became part of the Département of Haut-Rhin. After Napoleon's defeat and the Congress of Vienna, Lamboing was assigned to the Canton of Bern in 1815. A village school house was built in 1863. During the late 19th century a watchmaker's workshop opened in the village. It was acquired by the Ebauches SA company in 1926 and continued making components for watches until 1981. Beginning in the 1970s the village's population began to grow as commuters settled in Lamboing.

It has always been part of the parish of Diesse. When Diesse converted to the new faith of the Protestant Reformation between 1530 and 1554, Lamboing converted as well.

Before the merger, Lamboing had a total area of 9.1 km (3.5 sq mi). As of 2012, a total of 3.56 km (1.37 sq mi) or 39.1% is used for agricultural purposes, while 4.93 km (1.90 sq mi) or 54.1% is forested. Of the rest of the land, 0.61 km (0.24 sq mi) or 6.7% is settled (buildings or roads).

During the same year, housing and buildings made up 3.2% and transportation infrastructure made up 2.9%. Out of the forested land, 50.5% of the total land area is heavily forested and 3.6% is covered with orchards or small clusters of trees. Of the agricultural land, 19.3% is used for growing crops and 9.9% is pastures and 9.1% is used for alpine pastures.

The former municipality is located on the Plateau de Diesse. It consists of the village of Lamboing and the hamlets of Les Moulins, Derrière-la-Chaux and Magglingen.

On 31 December 2009 District de la Neuveville, the municipality's former district, was dissolved. On the following day, 1 January 2010, it joined the newly created Arrondissement administratif Jura bernois.
