Baha-ad-Din Iran-Shah ibn Turan-Shah (Persian: بهاالدین ایران شاه, 1059–1101, r. 1096–1101), or better simply known as Iran-Shah, was one of the Seljuk rulers of Kerman. During his reign, his kingdom had been heavily reduced and only extended in Kerman and its surroundings. It was reported that he was killed by the Nizari Ismailis, the arch-rivals of the Seljuks.
