Azarmidokht was Sasanian queen (banbishn) of Iran from 630 to 631. She was the daughter of king (shah) Khosrow II. She was the second Sasanian queen; her sister Boran ruled before and after her. Azarmidokht came to power in Iran after her cousin Shapur-i Shahrvaraz was deposed by the Parsig faction, led by Piruz Khosrow, who helped Azarmidokht ascend the throne. Her rule was marked by an attempt of a nobleman and commander Farrukh Hormizd to marry her and come to power. After the queen's refusal, he declared himself an anti-king. Azarmidokht had him killed as a result of a successful plot. She was, however, killed herself shortly afterwards by Rostam Farrokhzad in retaliation for his father's death. She was succeeded by Boran.

Khosrow II, commonly known as Khosrow Parviz, is considered to be the last great Sasanian king (shah) of Iran, ruling from 590 to 628, with an interruption of one year.
