Blue Cloud Abbey was an American Benedictine monastery located near the town of Marvin, in Grant County, South Dakota.

Their purpose was to serve the local population of the region, primarily the Native Americans on the Indian reservations, for whom they also operated several schools.

It was raised to the rank of a semi-independent priory on 5 August 1952 and to a fully autonomous abbey on 21 March 1954, with Gilbert Hess, O.S.B., being elected as the community's first abbot.

The reason for closure was that the monastery had not been able to draw a sufficient number of new members, which led to an increasingly aging monastic community.

[4] After a final Mass on Sunday, 5 August 2012—the feast day of Our Lady of the Snows, the patroness of the abbey—it officially ceased operations, and all public liturgies and scheduled retreats were cancelled.
