Marienstern Abbey was a Cistercian nunnery in Mühlberg in Brandenburg, Germany. Since 2000 a small community of the Claretian missionary brothers have lived in the former abbey premises.
The abbey was founded in 1228 by the brothers Otto and Bodo of Ileburg. Henry III, Margrave of Meissen, made gifts to the new foundation and also granted his consent to convert the former parish church of Mühlberg into the monastic church.
The nunnery was secularised in 1539 during the course of the Reformation.
