Gerontius (Геронтий in Russian) (? — 1489), Metropolitan of Moscow (since 1473), writer.

Gerontius was the Bishop of Kolomna. In 1473, he was appointed Metropolitan of Moscow. In the late 1470s, he was in conflict with Ivan III, among other things, over the consecration procedures of the new churches. During the Great standing on the Ugra river in 1480, Gerontius spoke for resisting the Golden Horde to the very end. He adhered to a moderate position in dealing with heresies, which had already plagued Moscow and Novgorod.

In 1482, Gerontius left his post, though he would later return at the request of the Grand Prince.
