Bagrevand (also spelled Bagrewand) was a region of Armenia.
The Old Iranian etymology of the name is disputed. It is either derived from *bāγa.raivanta ("rhubarb garden") or baga-raēvanta-, which either means "the rich giver" (Mithra) or "the bounteous God" (Ahura Mazda).
It was ruled first by Mamikonians and then, in IX-XI centuries, by the Bagratuni family[1],.
It also had its own diocese, whose bishops probably included the theologian Yeznik of Kolb.
