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.
