Xu Shuzheng (11 November 1880 – 29 December 1925) was a Chinese warlord in Republican China. A subordinate and right-hand man of Duan Qirui, he was a prominent member of the Anhui clique. In 1919 Xu assumed command of the Northwest Frontier defence Army, which invaded newly independent Outer Mongolia in October. On November 17 he forced Outer Mongolia to withdraw its declaration of autonomy, thus temporarily bringing Mongolia back under Chinese control. In 1920, after Duan fell from power, Xu lost his position and moved his forces back to confront his enemies. He was replaced in Mongolia by Chen Yi, and Mongolia became independent again in early 1921 when Chinese forces were defeated by the Russian–Mongol army commanded by General Baron Roman von Ungern-Sternberg. Xu's forces were defeated in the subsequent Zhili–Anhui War and he was forced to take shelter in the Japanese embassy.

In December 1925, while traveling from Beijing to Shanghai by train, Xu was kidnapped by Zhang Zhijiang, a member of Feng Yuxiang's forces. He was assassinated at dawn the next day by Feng as revenge for the killing of Lu Jianzhang.
