Moutier District was one of the three French-speaking districts of the Bernese Jura in the canton of Bern with the seat being Moutier, the other two being Courtelary and La Neuveville. It had a population of about 23,098 in 2004. On 1 January 2010, the district lost its administrative power while being replaced by the Bernese Jura, whose administrative centre is Courtelary. Since 2010, it remains therefore a fully recognised district under the law and the Constitution (Art.3 al.2) of the Canton of Berne.
On 1 January 2026, the town of Moutier joined the canton of Jura. A Moutier District was created, with Moutier being the only municipality of the district. This measure is meant to be temporary, with long-term options still being debated.
On 1 January 2026, the town of Moutier was officially incorporated into the canton of Jura, which subsequently resulted in the creation of a new Moutier District, consisting only of the municipality of Moutier. The amendment to the cantonal constitution creating the district was approved by every municipality in Jura.
