Du Yuanying (杜元穎; 769–833), formally the Baron of Jian'an (建安男), was an official of the Chinese dynasty, serving as a chancellor during the reign of Emperor Muzong. His policy error while being chancellor was blamed for the imperial government's losing control over the circuits north of the Yellow River. While later serving as the military governor (Jiedushi) of Xichuan Circuit (西川, headquartered in modern Chengdu), he was further blamed for failure of discipline that caused his soldiers to provoke a major Nanzhao invasion against Xichuan, leading to his exile.
