Joannes or John Zonaras (Greek: Ἰωάννης Ζωναρᾶς, Iōánnēs Zōnarâs; fl. 12th century) was a Byzantine chronicler and theologian who lived in Constantinople. Under Emperor Alexios I Komnenos he held the offices of head justice and private secretary (protasēkrētis) to the emperor, but after Alexios' death, he retired to the monastery in the Island of Hagia Glykeria, (Incir Ada, in the Aegean Sea), where he spent the rest of his life writing books.
