Zhao'an (simplified Chinese: 诏安; traditional Chinese: 詔安; pinyin: Zhào'ān; Pe̍h-ōe-jī: Chiàu-an-koān) is a county in the municipal region of Zhangzhou, southernmost Fujian province, People's Republic of China.

In May 1907, county officials arrested, on suspicion of piracy, the local leaders of a movement called the "White Fan".

They escaped, rallied their followers, captured the top mandarin, and killed the sheriff.

The anti-dynastic rebels had been gaining in popular support in the Minnan-speaking south of Fujian since 1906; local government soldiers would not fight them.

Qing troops were dispatched from Fuzhou and Guangzhou, capitals of the two affected provinces.
