The Youyang anti-missionary riot (Chinese: 酉阳教案) occurred in Youyang, 365 kilometres (227 mi) southeast of Chongqing, Sichuan Province, China in 1865.
In 1862, a French mission arrived in Youyang and built church.
In February 1865, hundreds of angry crowds ransacked the church.
Two days later, about ten people got into a verbal argument with a French missionary, and beat him to death.
Sichuan viceroy ordered the death of a local and paid 80,000 taels of silver indemnity to the French.
