Macarius of Unzha was a 14th-century Russian Orthodox monk and wonderworker who lived from approximately 1349 to 1444. Born in Nizhny Novgorod, he entered monastic life at a young age and eventually established several monasteries across the Volga regions. Known for his intense asceticism and devotion, he sought solitude in the wilderness, often living as a hermit in caves. He is remembered for his spiritual leadership, his role in converting various local groups to Christianity, and the numerous miracles attributed to his intercession.
