Ipsach is a municipality in the Biel/Bienne administrative district in the canton of Bern in Switzerland.

[3] The area around Ipsach was often settled during the neolithic, Bronze Age and Hallstatt eras.

The former bogs and peat moss near the village are full of prehistoric artifacts.

The settlements were part of the Herrschaft of Nidau but St. Alban's Monastery in Basel also owned land and rights in Ipsach.

In 1335, the owner of the Herrschaft, the Knight Cuno von Sutz sold Ipsach and Wiler to the Counts of Neuchâtel-Nidau.

Under Bernese rule, Ipsach and Wiler were part of the bailiwick of Nidau.

The village's location along the lake made it easy for residents to reach the towns of Biel and Neuchâtel.

Beginning in the 1950s, Ipsach became a suburb of Biel and its population began to grow rapidly.

In the 1980s a community center, a church and sport facilities were all built for the growing population.
