Joseph Marchand (August 17, 1803 - November 30, 1835) was a French missionary in Vietnam, and a member of the Paris Foreign Missions Society. Marchand was born in Passavant, in the Doubs department of France. In 1833, he joined the Le Van Khoi revolt by Le Van Khoi, son of the late governor of southern Vietnam Le Van Duyet. Khoi and Marchand vowed to overthrow Emperor Minh Mang and replace him with My Duong, the son of Minh Mang's late elder brother Nguyen Phuc Canh, who were both Catholics. Marchand and Khoi appealed to the Catholics to join in overthrowing Minh Mang and installing a Catholic emperor. They quickly seized the Citadel of Saigon and the uprising lasted two years. He was arrested in 1835 in Saigon and martyred, by having his flesh pulled by tongs (the torture of the hundred wounds).
