Michael Tzamantouros Laskaris (Greek: Μιχαήλ Τζαμάντουρος Λάσκαρις) was a Byzantine aristocrat and military commander.
[1] Michael and his brother Manuel bore the surname of Tzamantouros (Τζαμάντουρος),[1] likely indicating that they had a different mother than Theodore and his other siblings.
[1] On the accession of Theodore II Laskaris (r. 1254–1258) the two brothers were recalled to the court; while Manuel became a monk, Michael received the title of protosebastos and held unspecified military commands.
Michael was briefly exiled to Prusa, but quickly recalled by Palaiologos, who named him megas doux after the recapture of Constantinople.
[1] The post held command of the imperial navy, but Michael Laskaris, likely on account of his advanced age, never exercised this role, which instead went to the protostrator Alexios Doukas Philanthropenos.
