Ali Mardan Khan Bakhtiari

Ali Mardan Khan Bakhtiari (Persian: علی‌مردان‌خان بختیاری, romanized: Alī-Mardān Khān-e Bakhtīārī) was the Bakhtiari supreme chieftain (ilkhani) of the Chahar Lang branch, and major contender for supremacy in western Iran after the death of Nader Shah in 1747.

He was the autonomous ruler of Golpayegan (1749–1751) and Isfahan (1750–1751), assuming the title of Vakil-e daulat ("deputy of the state"), with the Safavid prince Ismail III as a figurehead that legitimized his rule. He was, however, driven back by Karim Khan Zand's forces, and after a number of clashes throughout the years, was murdered by two Zand chieftains at his own encampment, in 1754.
