Li Gao (Chinese:李暠; 351–417), courtesy name Xuansheng (玄盛), nickname Changsheng (長生), formally Prince Wuzhao of (Western) Liang ((西)涼武昭王), was the founding duke of the Chinese state Western Liang. (While he claimed only the title of duke during his reign, he was posthumoustly honored with the princely title.) He was initially a Northern Liang official, but in 400, he seceded from Northern Liang's prince Duan Ye's rule and established his own independent state. His state only lasted for 21 years, but his descendants would remain key officials and nobles throughout Northern Wei, Western Wei, Northern Zhou, and Sui dynasty, and one of them, Li Yuan, would found the Tang dynasty in 618. After the founding of the Tang dynasty, he was posthumously honored as Emperor Xingsheng (興聖皇帝).
