John Tornike was a 10th-century Georgian general and monk who played a crucial role in establishing the Iviron Monastery on Mount Athos. Born into a noble family close to the Bagrationi dynasty, he held the rank of eristavi and later received the Byzantine title of patrikios. After resigning his military post around 963, he entered monastic life under the name Ioane. He is remembered for his military service to the Byzantine Empire and his leadership in founding a significant center for Georgian Orthodox culture.
