'''Cem Sultan''' (also spelled '''Djem''' or '''Jem''') or '''Sultan Cem''' or '''Şehzade Cem''' (22 December 1459 – 25 February 1495, {{IPA|tr|ˈdʒem sulˈtaːn|pron}}; {{langx|ota|جم سلطان|Cem sulṭān}}; {{langx|tr|Cem Sultan}}; {{langx|fr|Zizim}}), was a claimant to the Ottoman throne in the 15th century.

Cem was the third son of Sultan [[Mehmed the Conqueror|Mehmed II]] and younger half-brother of Sultan [[Bayezid II]], and thus a half-uncle of Sultan [[Selim I]] of Ottoman Empire.

After being defeated by Bayezid, Cem went in exile in Egypt and Europe, under the protection of the [[Mamluk Sultanate|Mamluks]], the [[Knights Hospitaller of St. John]] on the island of [[Rhodes]], and ultimately the [[Pope]].
