Euphrosynus of Pskov was a Russian monk who lived from approximately 1386 to 1481. Originally named Eleazar, he joined the Snetogorsky Monastery near Pskov before transitioning to a life as a hermit around 1425. During his time in seclusion, he experienced religious visions that drew followers to him, eventually leading to the establishment of the Yelizarov Convent. He was recognized as a wonderworker and was later canonized as a saint during the Makaryev Sobor in 1549.
