Li Gao or Li Hao (Chinese: 李暠; 351–417), courtesy name Xuansheng (玄盛), nickname Changsheng (長生), also known by his posthumous name as the Prince Wuzhao of Western Liang (西涼武昭王), was the founding duke of the Chinese Western Liang dynasty during the Sixteen Kingdoms period.

He had, for a time, lived in the same house with his half-brother Song Yao and Guo Nen (郭黁), a minister of Later Liang's founding emperor Lü Guang known for his magical and prophetic abilities.

Guo once told Song, "Your place will be among the most honored of all subjects, but Mr. Li will one day found an independent state.

After Lü Guang's official Duan Ye, with support from the generals Juqu Nancheng (沮渠男成) and Juqu Mengxun, broke away from Later Liang and established Northern Liang in 397, Li Gao became a county magistrate under Duan Ye's governor of Dunhuang Commandery (roughly modern Dunhuang, Gansu), Meng Min (孟敏).

Initially, Li Gao was hesitant, but Song advised him to accept, stating to him that a pony with a white forehead had just recently been born.

At the urging of Song and Zhang Miao (張邈), however, Li Gao first sent messengers to flatter Suo, and instead made a surprise against Suo, defeating him and forcing him to flee back to the Northern Liang capital Zhangye (張掖, in modern Zhangye, Gansu).

In 405, Li Gao claimed additional honorific titles, and at the same time, while not renouncing Later Qin, also sent messengers to Jin, requesting to be a vassal.

In 411, Juqu Mengxun, despite the prior peace agreement, made a surprise attack on Western Liang.

Li Gao guarded his capital and refused to engage Juqu Mengxun, who was then forced to withdraw when his army ran out of food supply.
