Cheng Yi (程异), courtesy name Shiju (師舉), was a Chinese economist and politician of the Tang dynasty, serving as a chancellor during the reign of Emperor Xianzong. Like colleague Huangfu Bo, he was perceived to have risen to the chancellorship due to his ability to obtain revenues for the emperor, but unlike Huangfu, traditional accounts of his personal character were largely positive.
