Alexios Komnenos Strategopoulos (Greek: Ἀλέξιος Κομνηνὸς Στρατηγόπουλος) was a Byzantine aristocrat and general who rose to the rank of megas domestikos and Caesar. Distantly related to the Komnenian dynasty, he appears in the sources already at an advanced age in the early 1250s, leading armies for the Empire of Nicaea against Epirus. After falling out of favour and being imprisoned by Theodore II Laskaris, Strategopoulos sided with the aristocrats around Michael VIII Palaiologos, and supported him in his rise to the throne after Theodore II's death in 1258.
He participated in the Pelagonia campaign in 1259, going on to capture Epirus, but his successes were undone in the next year and he was captured by the Epirotes. Released after a few months, he led the unexpected reconquest of Constantinople from the Latin Empire in July 1261, restoring the Byzantine Empire. He was captured again by the Epirotes in the next year and spent several years in captivity in Italy, before being released. He retired from public affairs and died in the early 1270s.
