Mar Shemʿon V (died September 1502) was the patriarch of the Church of the East from 1497 until his death.
[4] Probably in 1499, Shemʿon V received a pair of messengers from the Indian church requesting bishops.
The patriarch consecrated Thomas and John, two monks of the monastery of Mar Awgin, as bishops and dispatched them to India with letters of authentication.
Thomas returned not long after with gifts from the Indian Christians, while John remained there as bishop.
His election may have represented a reaction to the policies of Shemʿon IV favouring his own family.
