Theognostus (Russian: Феогност, Ukrainian: Теогност; died on March 11, 1353) was Metropolitan of Kiev and all Rus'. Theognostus was born in Constantinople and later in his life became Peter's successor as Metropolitan of Kiev and all Rus'. He chose Moscow as his primary seat after he had lived for several years in Volodymyr-Volynskyi in Volynia. In 1353, feeling that his days were numbered, Theognostus recommended Alexius (Bishop of Vladimir) his successor. Theognostus was buried in the Cathedral of the Dormition in Moscow. He was canonized by the Russian Orthodox Church in the 19th century.
