Name Osan came to be called by its current name in 1914, at the time of a general reorganization of local governments under Japanese rule. At that time it became Osan-myeon, part of Suwon. This name in turn was taken from that of a local stream, the Osancheon. However, prior to the Japanese occupation, the name had been rendered in hanja as 鰲山, meaning "soft-shelled turtle mountain." Because of the complexity of the 鰲 ("o") character, and because crows were abundant in the area, the Japanese changed the name to 烏山, meaning "crow mountain school."
