Münsingen (German pronunciation: [ˈmʏnzɪŋən] ; Highest Alemannic: Münsige) is a municipality in the Bern-Mittelland administrative district in the Canton of Bern in Switzerland. On 1 January 2013 the former municipality of Trimstein merged into Münsingen, and on 1 January 2017 the former municipality of Tägertschi also merged.

The village lies on the River Aare between the cities of Bern and Thun.

Münsingen developed from a Celtic village first settled in around 400 BC. The origin of the name is unclear, though attributed to the Alamanni. During the early and middle La Tene era the residents of the village built about 220 tombs along the Aare river. Some of the men were buried with their weapons and the women and children were buried with jewelry.
