Wang Cong'er (Chinese: 王聰兒; pinyin: Wáng Cōng'ér, c. 1777–1798) was a female Chinese leader of anti-Manchu White Lotus Rebellion along with Wang Nangxian during the reign of the Qing dynasty.
The contemporary records of the Qing Court stated that "the deadliest of all the rebels are those led by Madam Wang, wife of Qi" and "it is said that all the rebel factions from Hubei and Shanxi were stirred up by Wang".
The Qing General Ming Liang eventually recruited local landlords to build forts and lock civilians inside whenever rebels were in the area, cutting off support from civilian sympathizers who were a key part of the rebels' supply chain.
In 1798, the Qing forces, with an increased number of warriors, ambushed Wang Cong'er and her fighters in the mountains near Yunxi, Hubei.
Despite being defeated, Wang Cong'er has been credited with creating a precedent for revolts against Chinese imperial rule.
