The population was 79 at the 2020 census. When the Northern Pacific Railway built its line through Adams County, they established a station where Hatton is and built a section and pump house. Prior to 1890, the station was named Twin Wells after the two wells that were drilled to water the railroad employees. In 1890, James Bronson established the first store and at the same time the post office was established with the name "Hatton". The name for the town was derived from the last names of the first postmistress, Belle Sutton, daughter of a local settler, and her new husband John Hackett, a Northern Pacific Railway agent from Twin Falls, Idaho. Bronson's store was purchased by Otis Algoe in 1897 who subsequently became postmaster.
