Jalal al-Din Kötürüm Bayezid (Old Anatolian Turkish: ) was Bey of Candar from 1361 until 1383.
At the time of his enthronement, the principality had two powerful neighbors; the Ottoman Empire to the west and the Beylik of Eretna under Kadñ Burhaneddin to the east, which made it a great challenge to maintain his dominion. Additionally, it was also a great challenge on the Black Sea coast where the Republic of Genoa and the Republic of Venice had interests.
Celâleddin Bayezid died in 1385.
