John II Megas Komnenos (Greek: Ιωάννης Β΄ Μέγας Κομνηνός, Iōannēs II Megas Komnēnos) (c. 1262 – 16 August 1297) was Emperor of Trebizond from 1280 to 1297. He was the youngest son of Emperor Manuel I and his third wife, Irene Syrikaina, a Trapezuntine noblewoman. John succeeded to the throne after his full-brother George was betrayed by his archons on the mountain of Taurezion. It was during his reign that the style of the rulers of Trebizond changed; until then, they claimed the traditional title of the Byzantine emperors, "Emperor and Autocrat of the Romans", but from John II on they changed it to "Emperor and Autocrat of all the East, the Iberians, and the Transmarine Provinces", although Iberia had been lost in the reign of Andronikos I Gidos.

John is the first ruler of Trebizond for whom we know more than a few incidents and hints; there is enough information to compose a connected narrative of the first part of his reign. The chronicle of Michael Panaretos, which is often terse and even cryptic, is relatively full for John's reign, and external sources add further details to Panaretos' account. Emperor John II faced many challenges to his rule, which partly explains his marriage to the daughter of the Byzantine emperor Michael VIII Palaiologos.

This insecurity may explain the sole instance where two Emperors of Trebizond appear on the coins of this polity: John and his oldest son, Alexios. By associating himself with his son Alexios on these coins, John may be advertising his choice for his successor.

John was born ca. 1262/3, the son of Manuel I (reigned 1238–1263) and his wife, Irene Syrikaina.
