Zhang Han (died c. June or July 205 BC[1]) was a Chinese military general of the Qin dynasty.
In 209 BC, the Dazexiang uprising broke out under the leadership of Chen Sheng and Wu Guang and sparked off a series of rebellions against the Qin dynasty throughout China.
Zhou Wen (周文), one of Chen Sheng's deputies, managed to lead a vanguard force that came close to Xianyang, the Qin capital, alarming the emperor Qin Er Shi, who called for a meeting with his subjects to discuss how to counter the rebels.
The emperor approved Zhang Han's proposal and appointed him as a general, putting him in charge of leading Qin forces to fight the rebels.
The Qin forces under Zhang Han continued to advance eastward and destroyed Chen Sheng's rebel group.
When Zhang Han sent Sima Xin to request reinforcements from Xianyang, the emperor refused to send aid after being deceived by Zhao Gao.
