Moutier-Grandval Abbey was a Benedictine abbey near the villages of Moutier and Grandval in today's Bernese Jura, Canton of Bern in Switzerland. It was founded around 640, when Grandval already existed; Moutier grew up around the abbey.

Moutier is a municipality in Switzerland. Currently, the town belongs to the Jura bernois administrative district of the canton of Bern. On 28 March 2021, the population voted to secede from the canton of Bern and join the Canton of Jura; the decision however is not immediately operative and entails a lengthy process of transfer of competences between cantonal authorities.
