Nicholas Komnenos Angelos Doukas Bryennios Maliasenos (Greek: Νικόλαος Κομνηνός Ἄγγελος Δούκας Βρυέννιος Μαλιασηνός) was a Byzantine Greek nobleman and magnate active in the region of Volos in Thessaly the second half of the 13th century.
Nicholas was the son of the first attested member of the Maliasenos family, Constantine, a magnate in Thessaly who married Maria, the daughter of Michael I Komnenos Doukas, ruler of Epirus.
Initially under the Epirote rulers, Nicholas was confirmed in his possessions by the Byzantine emperor Michael VIII Palaiologos as well.
[3] Nicholas married Anna Komnene Doukaina Palaiologina Philanthropene, a niece of Michael VIII Palaiologos, in ca.
[4] This marriage, as well as the removal of the Ilarion Monastery at Halmyros from the purview of the Monastery of Makrinitissa, founded by Nicholas' father, by the Despot of Epirus Michael II Komnenos Doukas, seems to indicate a shift in the family's allegiance to the then Empire of Nicaea.
