Sultan Khalil Mirza (Azerbaijani and Persian: سلطان خلیل میرزا) was a sultan of the Aq Qoyunlu State, ruling from 6 January 1478 to July 1478.^[1]

He was son of Uzun Hasan and Seljuk Shah Khatun. He was appointed as the governor of the Persian province during his princely years. He took power when his father, Uzun Hasan, passed away on January 6, 1478. In his early years, he had a fight with his brothers and uncle in the throne. He captured his younger half-brother Maqsud Beg (son of Despina Khatun) and executed him. His other younger full brothers Yaqub Beg and Yusuf Beg were exiled. In the same year, he defeated his uncle Murat Bey Bayandur and reached the height of his power. On the order of Sultan Yaqub, H. 14 Rebiül was executed (June 15, 1478) on a Monday. His half-brother Ughurlu Muhammad was taken by Ottoman Sultan Mehmed II and married his daughter Gevherhan Hatun. Their son Ahmad Beg finally took the throne but died in battle shortly after.

It is known that he has two sons from an unknown woman.^{[citation needed]}
