Madiswil is a municipality in the Oberaargau administrative district in the canton of Bern in Switzerland.

In 1406, the increasingly impoverished Counts of Kyburg gave the high court rights to Bern.

As part of the settlement after the war, in 1447 Bern acquired partial rights over the village and surrounding land.

During the 16th century the village had a series of conflicts with St. Urban's Abbey over ownership and use rights to several boggy meadows near the Langeten river.

After the 1798 French invasion and the creation of the Helvetic Republic, Madiswil, without Leimiswil, became part of the Langenthal District.

This was the first factory of what became the Ammann company, which is now a large multinational with 2,900 employees that builds construction equipment.

[5] In 1889, the Langenthal-Huttwil-Wolhusen railway built a station in Madiswil, which made it easy for commuters to work in nearby Langenthal.

At the beginning of the 21st century the main village has become a commercial and industrial center for the surrounding rural hamlets.

It consists of the village of Madiswil and the hamlets of Mättenbach and Wyssbach and the former municipalities of Gutenburg, Kleindietwil and Leimiswil.
