Michael Komnenos Tornikes Palaiologos Asanes

Michael Komnenos Tornikes Palaiologos Asanes, also called Michael Asen, was a fourteenth-century Byzantine aristocrat and administrator, the only known son of Constantine Palaiologos Asen and grandson of Bulgarian Tsar Ivan Asen III. He married Irene Komnene Kantakouzene Palaiologina Asenina; the couple appears in a miniature in the 1330 typikon of the Theotokos Bebaia Elpis convent in Constantinople.

Arrested with his father by Alexios Apokaukos in 1342, he later served as governor of Lesbos, probably around 1347. Nikephoros Gregoras composed an elegy on his death.
