Alexander Komnenos Asen
Alexander Komnenos Asen was a Bulgarian noble in the Serbian Empire, the son of Despot John Komnenos Asen and nephew of Tsar Ivan Alexander. On his father's death, probably in 1363, he succeeded as sebastos and lord of Kanina and Valona on the Adriatic coast.
He soon lost both cities to the Albanian lord Andrea II Muzaka. He is thought to have fallen at the Battle of the Maritsa on 26 September 1371, and by 1372 his lands belonged to Balša II.
