Manuel the Armenian (), was a prominent Byzantine general of Armenian origin, active from circa 810 until his death. After reaching the highest military ranks, a palace conspiracy forced him to seek refuge in the Abbasid court in 829. He returned to Byzantine service the next year, receiving the position of Domestic of the Schools from Emperor Theophilos, who had married his niece Theodora. Manuel remained in the post throughout Theophilos's reign, and reportedly saved the emperor's life in the Battle of Anzen in 838.

This appointment is, however, most likely a misreading of the primary source, according to the editors of the Prosopographie der mittelbyzantinischen Zeit. According to the history of Michael the Syrian, at about the same time Manuel was responsible for the negotiations with the Khurramite refugees and their leader, Nasr, who became baptized as Theophobos in Byzantine service; however, Michael's chronology of this episode is confused and of doubtful accuracy.
