Alexios Mosele or Musele/Mousele (Μουσελέ) was a Byzantine aristocrat and general, chosen by Emperor Theophilos for a time as his heir, betrothed to his daughter Maria and raised to the supreme dignity of Caesar. He campaigned in the Balkans, recovering territory from the Slavs, and fought with some success in Sicily against the Arabs. Recalled to Constantinople on suspicion of plotting to usurp the throne, he was imprisoned but later pardoned and allowed to retire to a monastery, where he spent the remainder of his days.

Theophilos was the Byzantine Emperor from 829 until his death in 842. He was the second emperor of the Amorian dynasty and the last emperor to support iconoclasm. Theophilos personally led the armies in his long war against the Arabs, beginning in 831.
