Michael Lachanodrakon (; died 20 July 792) was a distinguished Byzantine general and fanatical supporter of Byzantine Iconoclasm under Emperor Constantine V (r. 741–775). As a result of his iconoclast zeal, in 766 he rose to high office as governor of the Thracesian Theme, and instigated a series of repressive measures against iconophile practices, particularly targeting the monasteries. A talented general, he also led a series of campaigns against the Arabs of the Abbasid Caliphate before being dismissed from office in about 782. Restored to imperial favour in 790, he fell at the Battle of Marcellae against the Bulgars in 792.
