Shah Ghazi Rustam (Persian: شاه غازی رستم), was king of the Bavand dynasty of Mazandaran, ruling from 1142 to 1165. He expanded the borders of the kingdom at the expense of his neighbors, particularly the Ismailis and the Seljuks. He established a Bavandid presence in Gilan as a result of his frequent vengeful raids against the Ismailis, who had assassinated his son and heir, Girdbazu. He also brought Qumis and Ray under Bavandid control during his wars against the Seljuks and the Karakhanids.
Shah Ghazi's reign represented the pinnacle of Bavandid power and influence in Iran, and Shah Ghazi himself was considered the most illustrious king of the dynasty.
