Hormizd II (also spelled Hormozd or Ohrmazd; 𐭠𐭥𐭧𐭥𐭬𐭦𐭣) was king (shah) of the Sasanian Empire. He ruled for seven years and five months, from 303 to 309. He was a son and successor of Narseh (293-303).
During his reign, the Kingdom of Armenia had recently declared Christianity as its official religion, thus leaving its ancient Zoroastrian heritage that it shared with Sasanian Iran.
