Khosrov IV (Armenian: Խոսրով Դ; died 415 or 418), called Khosrov III in some sources,[1] was a noble of the Arsacid dynasty who served as the Sasanian client king of Armenia from 384/385 until 389 and again from 414 to 415 or 417 to 418. He was appointed king of Armenia by the Sasanian king, who gave Khosrov his sister in marriage. During his reign, Armenia was partitioned into Roman and Sasanian sectors with the Peace of Acilisene in 387. Khosrov reigned in the eastern, Sasanian part, while his relative Arshak III reigned in the western, Roman part. He reigned for about five years before being denounced by the Armenian nobility for conspiring with Rome and deposed and deported to Iran. He was briefly restored to the throne after the death of his brother and successor Vramshapuh, but he died not long after that.
