Ninth-century Byzantine archimandrite and exarch. As a supporter of the deposed patriarch ignatius, Theognostos was sent to Rome to represent the patriarchs' interest; he remained there until 868, when he returned with a papal message for the emperor. Ignatius made him archimandrite of the Pege Monastery and skeuophylact of the Great Church. He made a second journey to Rome, after which nothing is known about him. He is generally credited with a Report to Pope nicholas i on the ecclesiastical situation in Constantinople between 858 and 861; but this is actually the Letter of Appeal sent by Ignatius to the Pope, which Theognostos probably helped to compose. A panegyric on the saints and a short sermon of the Koimsis of the Mother of God have also been attributed to him.
