Michael of Klopsk (Russian: Михаил Клопский, romanized: Mikhail Klopsky; died 1456)[1] was a Russian Orthodox monk and fool for Christ associated with the Klopsky Monastery of the Holy Trinity,[2] located near Novgorod on the river Veryazha.

[3] According to Valentin Yanin,[3] Michael was the son or grandson of Dmitry Mikhailovich Volyn-Bobrok ("Little Beaver"),[4] a hero of the Battle of Kulikovo, and Anna Ivanovna, daughter of Grand Prince Ivan II of Moscow,[5] and sister of Dmitry Donskoy.

[7] Although folklorish in nature, it provides the earliest literary evidence for Michael's activities in the monastery.

During the period of the Muscovite–Lithuanian Wars, a mysterious fool-for-Christ's-sake appeared in the Monastery of the Holy Trinity.

Among the miracles attributed to the saint by the hagiography are the conversion of robbers, one of whom became the monk Dorofey, the discovery of an inexhaustible fountain, the prediction of weather, and various other acts of clairvoyance and prophecy.
