Khosrau IV or Khurrazadh is Sasanian king from 631 to 632.

Little is know about his rule.

He appears to have ruled during a time of upheaval and chaos across the Sassanian Empire the 7th century has the century where Iran has plunged into its "dark ages".

He is possibly the son of Khosrau II.

His rule seems to coincide with other pretenders such as Hormizd VI so it is likely that he rules a district or province rather than the Empire in its entirety.

He is succeeded by Yazdegerd III, the final ruler of the Sasanian Empire.
