Hatton is a small incorporated town in Adams County, Washington, United States. 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.

Hatton finally began to grow after 1901 and was platted on April 30, 1901 by James Bronson. By that time the town had four large warehouses, five stores, two hotels, a bank and a school. A newspaper, The Hatton Hustler was established during that time. Hatton was officially incorporated on July 31, 1907.

According to the United States Census Bureau, the town has a total area of 0.37 square miles (0.96 km), all of it land.

Hatton is located within the region of Washington known as the Channeled Scablands and is situated on the west slope of the Providence Coulee with the Paradise Flats to the west and the Michigan Prairie to the east. The coulee was utilized by the Northern Pacific Railway for the construction of their main line from Portland, Oregon to Spokane.
