Alexios V Megas Komnenos was very briefly Trapezuntine emperor in April 1460, succeeding his uncle John IV, until his deposition by his other uncle, David. Alexios was the son and only known child of Alexander, a brother of John IV and David. Alexander served as co-emperor with John IV but died prior to 1460, which left the young Alexios as John IV's heir. Almost immediately after Alexios's accession, David, with support of the influential Kabazites family, deposed Alexios and took the throne for himself.
