John the Georgian of Khandzta

Venerable John the Georgian (Ioane Kartveli) of Khandzta (first half to mid-⁠ninth century) was a monk of the Khandzta Monastery, in the Klarjeti desert. He is venerated as a saint in the Synaxis of the Venerable Fathers and Mothers of Klarjeti of the Orthodox Church of Georgia, canonized on 17-18 October 2002; he is commemorated on 5 October (old calendar).

His name is recalled in the Life of Venerable Gregory of Khandzta, written in the year 951. George Merchule, the author of the Life, says that "the life of the blessed Gregory was written at Khandzta through the joint zeal of all three: the abbot of Khandzta (Venerable Theodore the Georgian), his brother John and the author of this book, George Merchule." John was thus the brother of the abbot of Khandzta at the time of writing and one of those who put into writing the memory of Venerable Gregory, founder of the monasteries of Klarjeti. No other news of his life survives.
