Hanaoka Seishū (華岡 青洲; October 23, 1760 – November 21, 1835) was a Japanese surgeon of the Edo period with a knowledge of Chinese herbal medicine, as well as Western surgical techniques he had learned through Rangaku (literally "Dutch learning", and by extension "Western learning"). Hanaoka is said to have been the first to perform surgery using general anesthesia.
