Zhang Xiong (張雄) (d. September 18, 893) was a Chinese military general and politician during the Tang Dynasty. He from 886 and on, controlled an army that initially roved in the lower Yangtze River region and became a key player in the power struggles between various warlords for the control of Huainan (淮南, headquartered in modern Yangzhou, Jiangsu) and Zhenhai (鎮海, headquartered in modern Zhenjiang, Jiangsu) Circuits. Zhang eventually settled in at Shangyuan (上元, in modern Nanjing, Jiangsu) in 887 and controlled the area until his death in 893. Background Zhang Xiong was originally from Lianshui (漣水, in modern Huai'an, Jiangsu), and he served as an officer at Ganhua Circuit (感化, headquartered in modern Xuzhou, Jiangsu), which Lianshui belonged to. Once, when fellow officer Feng Hongduo, who was also from Lianshui, was accused of impropriety by circuit administrators, Zhang spoke on his behalf, and Zhang's doing so caused Ganhua's military governor (Jiedushi) Shi Pu to suspect both of them. In 886, knowing that Shi suspected them, Zhang and Feng gathered 300 men and left Ganhua with them, crossing the Yangtze River to attack Su Prefecture (蘇州, in modern Suzhou, Jiangsu), which then belonged to Zhenhai Circuit.

As Zhou had heard that Xu Yue (), an officer under Zhou's rival Gao Pian the military governor of Huainan, had a strong army, he induced Xu to attack Su Prefecture, promising to give the prefecture to him if Xu were successful. In summer 887, Xu attacked Zhang; Zhang was unable to withstand the attack, and he took his army east out to the East China Sea. He sent his officer Zhao Hui () with part of the army and part of the fleet west on the Yangtze to take over Shangyuan, and Zhao was able to do so. Meanwhile, Huainan's capital Yang Prefecture () had become embroiled in internecine warfare, as the officer Bi Shiduo, fearful that Gao's trusted sorcerer Lü Yongzhi was about to kill him, mutinied and captured Yang Prefecture, taking Gao under his control. Zhang used this opportunity to approach it, stopping his army at Dongtang (東塘, in
