Mehr Ali Beg Javanshir (Persian: مهرعلیبیگ جوانشیر) was the son of the Panah Ali Khan, the khan of the Karabakh Khanate, whom he according to historian Ahmad Beg Javanshir, briefly succeeded.
However, this event is not mentioned by historians Abbasgulu Bakikhanov and Adigozal Beg.
Shortly after his succession, Mehr Ali Beg was reportedly ousted by brother Ibrahim Khalil Khan, and was later killed either by Aghasi Khan and his son or only by the latter's eldest son Ahmad Khan.
[1] While the historians Abbasgulu Bakikhanov and Adigozal Beg report that Mehr Ali Beg's brother Ibrahim Khalil Khan succeeded their father as khan, the historian Ahmad Beg Javanshir reports a different story.
After marrying the sister of Umma Khan V of the Avar Khanate, Ibrahim Khalil Khan established his authority in Karabakh.
