Hormizd I Kushanshah was Kushanshah of the Kushano-Sasanian Kingdom from 275 to 300. His reign was marked by his rebellion against his brother and suzerain the Sasanian King of Kings Bahram II (r. 274–293).
Hormizd I Kushanshah was notably the first Kushano-Sasanian ruler to claim the title of "Great Kushan King of Kings" instead of the traditional "Great Kushan King". This displays a noteworthy transition in Kushano-Sasanian ideology and self-perception and possibly a direct dispute with the ruling branch of the Sasanian family. By the time of Bahram II's death in 293, Hormizd I Kushanshah's rebellion had been suppressed; he continued to rule until his death in 300, and was succeeded by his namesake Hormizd II Kushanshah.
