Rüeggisberg is a municipality in the Bern-Mittelland administrative district in the Canton of Bern in Switzerland.

Rüeggisberg is first mentioned in 1075 as mons Richeri. In 1224 it was mentioned as Ruogersperg.

The oldest trace of a settlement is the Roman road that likely passed through Rüeggisberg between Aventicum / Payerne and the Thun lake area. During the Middle Ages there were three fortifications in the area, Büffelhölzli, Ramsburg and Schlosschäle castles or forts. However no records remain of any of the three and only limited artifacts have been found.
