Bizhan or Bijan (Persian: بیژن) is one of the main Iranian heroes in the Shahnameh, the national epic of Greater Iran. Bizhan is son of Giv and Banu Goshasp and grandson of Goudarz and Rostam. Although he appears in almost all stories in the heroic age of Shahnameh, he has a significant role in the story of Bizhan and Manizhe, where he fell in love with Manizhe, the daughter of Afrasiab, the king of Turan and longtime enemy of Iran.
It has been suggested that Bizhan is a Parthian figure. Vizhan is the name of the grandson of Gotarzes I and the grandfather of Gotarzes II. According to Nöldeke, noble Parthian families who were guardians of Iranian national epics, later attributed some of the exploits of the ancient heroes to their own ancestors.
