Bolad (Mongolian: , , , d.1313), was an ethnic Mongol minister of the Yuan dynasty of China, and later served in the Ilkhanate as the representative of the Great Khan of the Mongol Empire and cultural adviser to the Ilkhans. He also provided valuable information to Rashid-al-Din Hamadani to write about the Mongols. Mongolists consider him a cultural bridge between East and West. He was ennobled by Emperor Renzong of Yuan as Duke of Ze (澤國公) in 1311 and Prince of Yongfeng (永豐郡王) in 1313, posthumously.
