Alexios II Megas Komnenos, Emperor of Trebizond (b. 1282)
Alexios II Megas Komnenos (Greek: Αλέξιος Μέγας Κομνηνός, romanized: Alexios Megas Komnēnos; Sept./Dec. 1282 – 3 May 1330), was Emperor of Trebizond from 1297 to 1330. He was the elder son of John II and Eudokia Palaiologina.

Alexios proved to be a skillful and energetic ruler, under whose rule the Empire of Trebizond reached the climax of its prosperity. He rebuffed the inroads of the marauding Turks, and adequately handled the encroachment of Genoa and Venice. He also cultivated the arts and sciences at his court serving as a patron to the Byzantine astronomer Gregory Chioniades and the scholar Constantine Loukites.
