Zhang Zuo (; died 355), courtesy name Taibo (), formally Prince Wei of (Former) Liang () was a ruler of the Chinese state Former Liang. He was the only ruler of Former Liang to formally declare a break from Jin Dynasty (266–420), and historical sources variously report him as having declared himself an emperor (per "Jin Shu") or a prince (per "Zizhi Tongjian"). He was commonly viewed as a usurper (having seized the throne from his nephew Zhang Yaoling after his brother Zhang Chonghua's death) and initially not acknowledged as a Former Liang ruler, but his brother Zhang Tianxi later nevertheless gave him the posthumous name of Wei.
