The nearby stream was named Idiot Creek after the community and was added to the official United States Board on Geographic Names list in 1977. About a half mile up Idiot Creek was a logging camp called Ryan's Camp, which was part of the salvage operations following the Tillamook Burn. Since the spot was so remote, it was said that only an idiot would work there, so the camp was popularly known as Idiotville. The name was eventually applied to the stream. Idiotville has been noted for its unusual place name.
