Zhang Hao (Chinese: 張顥; pinyin: Zhāng Hào) (died June 18, 908[1][2]) was a guard commander for late Chinese Tang dynasty warlord Yang Xingmi the Prince of Wu, who was the military governor (jiedushi) of Huainan Circuit (淮南, headquartered in modern Yangzhou, Jiangsu), and Yang Xingmi's son Yang Wo (Prince Wei of Hongnong) early in the Five Dynasties and Ten Kingdoms period. Along with fellow guard commander Xu Wen, he took over reins of the Hongnong state (which, in later times, would be known as Wu) by effectively putting Yang Wo under physical control. In 908, fearing that Yang Wo was about to seize power back and kill them, they assassinated him first. However, they then turned on each other, and Zhang was killed by Xu, who then took sole rein of Hongnong.
