This is an incomplete list of Christian religious houses in Saxony in Germany, extant and non-extant, and including houses of both men and women. Most religious houses in Saxony were suppressed during the Reformation in the 16th century, but some survived. A small number also survived the Communist period of the DDR, including the Cistercian nunnery of St. Marienthal Abbey in Ostritz founded in 1243. Since the reunification of Germany in 1990, a number of new religious communities have been established.
