Michael of Klopsk was a Russian Orthodox monk and a holy fool who lived during the 15th century. He was associated with the Holy Trinity Monastery, located near Novgorod on the Veryazha river. Historical accounts suggest he may have been a descendant of Dmitry Mikhailovich Volyn-Bobrok and Anna Ivanovna. During the Muscovite–Lithuanian Wars, he lived as an anonymous figure at the monastery before being identified by Prince Konstantin Dmitrievich in 1413. He is recognized as a saint within the Eastern Orthodox tradition.
