William Welton (1808–1858) was an English clergyman, physician, and surgeon. Born and raised in Wickham Market, Suffolk, England, Welton practiced as a surgeon for several years before shifting to study theology and become a medical missionary. He is credited with being the first Church Missionary Society doctor to go to China, as he went to Fuzhou (also Fuh-Chow or Foochow), China from 1849 to 1856. He was one of two missionaries whose actions instigated the Shen-kuang-szu Incident in 1850-1.
