Archbishop Arkadios II (d. 643) was the head of the Church of Cyprus during the 630s. He was a supporter of the Monothelitism formula also propounded by Patriarch Sergius I of Constantinople, Pope Honorius I, and Emperor Heraclius. Heraclius promptly sided with Monothelism and issued an Edict to all the metropolitan sees (probably the Ecthesis). When this Edict arrived in Cyprus, Arkadios added his signature to the list.
