Moutier-Grandval Abbey was a Benedictine abbey near the villages of Moutier and Grandval in the Jura bernois administrative district in the canton of Bern in Switzerland.

The abbot of Luxeuil, Saint Waldebert, sent Saint Germanus of Granfelden, who served 35 years as the first abbot, with Saint Randoald of Grandval as his prior.
Saint Randoald (Rancald, Randaut) (†21 February 675) was prior of the Benedictine monastery of Grandval in the Moutier valley, under saint Germanus.
According to the Life of Germanus of Grandval, Adalrich "wickedly began oppressing the people in the vicinity Sornegau of the monastery and to allege that they had always been rebels against his predecessors."
During the 1870s, Grandval played a major role in the Société Nationale de Musique, and was the most played composer in this society.
