Zhang Xuanjing (張玄靚 or 張玄靖) (350–363), courtesy name Yuan'an (元安), formally Duke Jingdao of Xiping (西平敬悼公, posthumous name given by Jin Dynasty (265-420)) or Duke Chong of Xiping (西平沖公, posthumous name used internally in Former Liang) was a ruler of the Chinese state Former Liang. He became the titular ruler at the young age of five after his violent uncle Zhang Zuo, who had seized the title from his older brother Zhang Yaoling and subsequently killed him, was himself killed in a coup. Zhang Xuanjing was addressed as Prince Chong of (Former) Liang (Chinese: (前)涼沖王)
The years of his rule were characterized by political instability, as he went through a progression of regents who overthrew each other -- Zhang Guan (張瓘), Song Hun (宋混), Song Cheng (宋澄), Zhang Yong (張邕), and finally his uncle Zhang Tianxi, who eventually had him killed and took over the title in 363. During Zhang Guan's regency, he temporarily used the title Prince of Liang, but after Song Hun overthrew Zhang Guan, he again used the Jin-created title of Duke of Xiping.
