Geshu Han (died December 1, 757), formally Prince Wumin of Xiping, is a general of the Chinese dynasty Tang Dynasty of Tuqishi (subordinate tribe of Tujue (Göktürks)) extraction.

He becomes a powerful general late in the reign of Emperor Xuanzong and in 756 becomes responsible for defending Tong Pass against the rebel forces of An Lushan.

After being forced by the chancellor Yang Guozhong to engage An's forces, he is defeated and subsequently kidnapped by his own subordinate Huoba Guiren to An's camp.

An tries to use him to get his subordinate generals Li Guangbi, Lai Tian, and Lu Gui to surrender as well, but when those generals refuse to do so, puts him under house arrest in Luoyang, the capital of An's newly established state of Yan.

In 757, after An's son and successor An Qingxu is defeated by Tang forces and forced to abandon Luoyang, An Qingxu executes Geshu and some 30 other captive Tang generals.
