Yao Qisheng (simplified Chinese: 姚启圣; traditional Chinese: 姚啟聖; pinyin: Yáo Qǐshèng; 1624–1683), courtesy name Xizhi (Chinese: 熙止; pinyin: Xīzhǐ), was a regional official, diplomat, and statesman during the reign of the Kangxi Emperor in Qing Dynasty China. Yao was a pivotal figure in the Qing empire's annexation of Taiwan.
Yao was born in the Shaoxing area of Zhejiang province during the waning years of the Ming dynasty. At age 20, he reputedly killed two soldiers who kidnapped a girl, and returned the girl to her family, earning him fame as a righteous figure in local lore. Due to having been wronged by local merchants, he joined the Qing army as a means to exact revenge. In 1663, Yao scored first in the local Civil Service Examinations, and became the county magistrate of Xiangshan County in Guangdong. In Xiangshan, Yao was known to have cleaned up finances of the local bureaucracy, which was mired in debt under his predecessor. However, several years later he was removed from the position, for unknown reasons, and returned to Zhejiang.
In 1674, Yao, along with his son, raised a small army of several hundred men to assist Giyesu, the Prince Kang, in the fight against Geng Jingzhong, who had revolted against Manchu rule.
On recommendation from Giyesu, Yao became entrusted by the Kangxi Emperor, who eventually appointed him Viceroy of Minzhe during a campaign against Ming Dynasty loyalists on Taiwan under the leadership of Zheng Jing. Yao led Qing forces to several victories on the Fujian coast, eventually forcing Zheng to retreat to the island of Taiwan proper.
