Constantine Podopagouros, Byzantine official
Constantine Podopagouros (Greek: Κωνσταντῖνος Ποδοπάγουρος; died 25 August 766) was a high-ranking Byzantine official and, with his brother Strategios, leader of a conspiracy against Emperor Constantine V (r. 741–775).

"Podopagouros" is a sobriquet that means "crabfoot". Very little is known about his life and career other than his involvement in the conspiracy against the emperor, which came to light in the summer of 766. According to Theophanes the Confessor, Constantine was then patrikios and logothetes tou dromou. Constantine and his brother, who at the time was commander of the elite tagma of the Exkoubitores, were the leaders of the conspiracy which, according to Theophanes, included nineteen high-ranking officials in total, including several senior provincial governors (strategoi). After the plot's discovery, the conspirators were publicly paraded and humiliated at the Hippodrome of Constantinople on 25 August 766, following which Strategios and Constantine were beheaded at the Kynegion, while the others were blinded and exiled. A few days later, the Eparch of the City Prokopios was also dismissed, followed by the deposition and exile of Patriarch Constantine II, after he was implicated by some clergymen in the conspiracy.In his chronicle, Theophanes portrays the conspiracy as part of a reaction against Constantine V's iconoclast policies, stating that some of the conspirators were adherents of the iconophile hermit Stephen the Younger of Mount Auxentios, whom the emperor had had publicly humiliated and executed the previous November. Modern scholarship on the other hand is not as clear as to the motivations of the emperor, i.e. whether the death of Stephen, or the humiliation and blinding of seventeen of the nineteen officials and other acts of persecution was due to his hardening stance against iconophile sentiment, or had political motives as a reaction to plots against his life (in which Stephen too may have been implicated).
