Lauperswil is a municipality in the administrative district of Emmental in the canton of Bern in Switzerland.

Lauperswil is first mentioned in 1275 as Loperswile.

Lauperswil and the surrounding area were inhabited during the Middle Ages and were part of the Herrschaft of Wartenstein. By the Late Middle Ages Trub Abbey was the largest landowner in the municipality. It was part of the high court of Ranflüh, which was acquired by Bern in 1408. It was part of the Trachselwald bailiwick until the reorganization following the 1803 Act of Mediation moved it into the Signau District. The first bridge over the Emme river in the municipality was built in 1552. The village of Zollbrück grew up around the bridge and toll station. The Bern-Langnau railroad built a station in Lauperswil in 1864, followed by the Burgdorf-Langnau railroad in 1881. The two railroads combined with a new road in 1899, brought factories and industry to the municipality. Many of these new factories settled in Zollbrück and Emmenmatt. Today, many of the factories are still in operation, though outside the industrial zones, agriculture still provides a number of jobs.

The village church was first mentioned in 1275. In 1284 it came under the authority of Trub Abbey and in 1294 joined the Abbey parish. In 1518 the church was rebuilt and in the following year the stained glass windows were added. In 1528, Bern adopted the new faith of the Protestant Reformation and secularized all of Trub Abbey's lands. The parish was dissolved and the village church came under the control of the Bern Minster.
