Chrysanthos of Madytos (Greek: Χρύσανθος ὁ ἐκ Μαδύτων; c. 1770 – 1846) was a Greek poet, chanter, Archimandrite, and Archbishop, born in Madytos. In preparation of the first printed books of Orthodox chant, he was responsible for a reform of the Byzantine notation within the New Music School of the Patriarchate, along with Gregorios the Protopsaltes and Chourmouzios the Archivist who transcribed the traditional repertory into the Chrysanthine notation.
