Hammon is a town in the U.S. state of Oklahoma, the majority of which is in Roger Mills County, but some of which extends into Custer County. It is located at the junction of Oklahoma State Highways 33 and 34.[3]
The town is named for Indian agent James H. Hammon, who was assigned to the Red Moon Agency near the future site of Hammon.[4] This was a subagency of the Cheyenne-Arapaho Agency at Darlington, north of Fort Reno, and his mission was to build a reservation school and to teach the Cheyenne and Arapaho to farm. His wife, Ida M. Hammon, was postmaster when a post office was established in their home on June 30, 1894.
The townsite was originally located in Custer County, but when the Wichita Falls and Northwestern Railroad (later known as the Missouri, Kansas and Texas Railway) laid track west of the town in 1910, the majority of the town was moved west into Roger Mills County to be near the railroad. On May 22, 1911, the board of county commissioners accepted the incorporation of the town.
The population was 479 at the time of the 2020 census.[5]
According to the United States Census Bureau, the town has a total area of 0.7 square miles (1.9 km2), all land.
Hammon is located southwest of the intersection of State Highway 33 and State Highway 34 in Southwestern Oklahoma, known for Oklahoma Tourism purposes as Great Plains Country.[6] The town is just west of the Washita National Wildlife Refuge, and just east of the Black Kettle National Grassland.
