List of Famous people with last name Asen

Michael II Asen, was Emperor (Tsar) of Bulgaria from 1246 to 1256 or 1257. He was the son of Ivan Asen II of Bulgaria and Irene Komnene Doukaina. He succeeded his half-brother, Kaliman I Asen. His mother or other relative must have ruled Bulgaria during his minority.

John Komnenos Asen was the ruler of the Principality of Valona from circa 1345 to 1363, initially as a vassal of the Serbian Empire, and after 1355 as a largely independent lord. Descended from high-ranking Bulgarian nobility, John was a brother of both Tsar Ivan Alexander of Bulgaria and Helena of Bulgaria, the wife of Tsar Stephen Dušan of Serbia. Perhaps in search of better opportunities, he emigrated to Serbia, where his sister was married. There, he was granted the title of despot by Stephen Dušan, who placed him in charge of his territories in modern south Albania.

Andronikos Asen was the epitropos of the Byzantine province of the Morea between 1316 and 1322.
