John I Axouchos of Trebizond
John I Komnenos Axouch (c. 1214–1238) was Emperor of Trebizond from 1235, the eldest son of the founder Alexios I and Theodora Axouchina. When Alexios died in 1222 the crown first passed to his son-in-law Andronikos I Gidos, whom John succeeded in 1235.
In 1238 he died playing tzykanion, the Byzantine polo-like game, after falling from his horse and being trampled. His heir Ioannikios was confined to a monastery, and his brother Manuel I became emperor.
