Al-Marzuban or Marzuban bin Rustam of Parim (Persian: مرزبان بن رستم پریمی), was the thirteenth ruler of the Bavand dynasty from 979 to 986.
In some sources, his name was changed to Rustam ibn al-Marzuban, which caused confusion among the historians, and made them think that they were two people.
However, according to the Qabus-nama made by the Ziyarid ruler Keikavus (who was of Bavandid descent), Sayyida Shirin was the niece of al-Marzuban.
al-Marzuban is then once again mentioned in sources, as the having deposed Shahriyar III, and restored himself as the ruler of the Bavand dynasty.
In 998, Shahriyar III returned to Tabaristan with Ziyarid aid, and wrested the Bavandid capital of Perim from al-Marzuban.
