Wang Gao (王郜) was a warlord late in the Chinese dynasty Tang Dynasty, who controlled Yiwu Circuit (義武, headquartered in modern Baoding, Hebei) after succeeding his father Wang Chucun in 895 until his defeat in 900.
It is not known when Wang Gao was born. His father Wang Chucun had become the military governor (Jiedushi) of Yiwu Circuit in 879, and during Wang Chucun's governance, Wang Gao became deputy military governor (副大使, Fudashi). After Wang Chucun's death in 895, the soldiers supported Wang Gao to be acting military governor. Then-reigning Emperor Zhaozong thus commissioned him as acting military governor, and then full military governor. In 897, Emperor Zhaozong gave Wang Gao the honorary chancellor designation Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事).
In 900, the major warlord Zhu Quanzhong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan), an archrival to Wang Gao's ally Li Keyong the military governor of Hedong Circuit (河東, headquartered in modern Taiyuan, Shanxi), sent his general Zhang Cunjing (張存敬) north to try to subdue Li Keyong's allies east of the Taihang Mountains. After first forcing Wang Rong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) to submit, Zhang attacked Yiwu Circuit. Wang Gao sent his uncle Wang Chuzhi to resist Zhang. Wang Chuzhi advocated building fences to try to impede the Xuanwu army's advancement, to tire it out, before engaging the Xuanwu army. However, the officer Liang Wen (梁汶), arguing that the Yiwu army had a numerical advantage, advocated an immediate confrontation. Wang Gao thus ordered one. Zhang, however, crushed the Yiwu army and killed over half of its soldiers; the remaining soldiers escorted Wang Chuzhi and fled back to Yiwu's capital Ding Prefecture (定州).
