Bolligen is a municipality in the Bern-Mittelland administrative district of the canton of Bern, Switzerland.

In the historical center is a twelfth-century church, with a benefice barn and parsonage from the 16th century.

During the 13th and 14th centuries, representatives of Bern and the Kyburg Counts often met in Bolligen for negotiations.

Following the Protestant Reformation in 1528, Bern secularized a number of monasteries around the Canton.

The Grauholz-Sädelbach woods near Bolligen became a popular summer retreat for Bern's patrician families.

Beginning in the 18th century, farmers in Bolligen began to grow hay in addition to the traditional grain.

The hay was sold to provide food during winter for the many dairy and cattle farms that were developing in the surrounding area.

The municipality remained a mostly rural town until the agglomeration of Bern spread into Bolligen in 1950s transforming it.

Bolligen lies northeast of Bern, its area connects the Worblental to the Emmental.

The "Lutzere" mountains form the watershed boundary between the Emme and the Aare rivers.

In 1980 and 1983, the small but heavily populated towns of Ittigen and Ostermundigen divided from Bolligen to form independent municipalities.

It consists of the village of Bolligen and the hamlets of Bantigen, Ferenberg, Flugbrunnen, Geristein and Habstetten.
