Hammon is a town mostly in Roger Mills County, Oklahoma, with a portion extending into Custer County, located sixteen miles east of the county seat of Cheyenne on State Highway 33.

Hammon is named for James H. Hammon, an Indian agent assigned to the Red Moon Agency, a subagency of the Cheyenne-Arapaho Agency, whose mission was to build a reservation school and teach the Cheyenne and Arapaho to farm.

Hammon's wife, Ida M. Hammon, served as postmaster when a post office was established in their home on June 30, 1894.

Settlers came to the Hammon area during the Cheyenne-Arapaho land opening of April 19, 1892, after the Cheyenne and Arapaho received 160-acre allotments under the Dawes Severalty Act of 1887.

The townsite originally lay within Custer County, but when the Wichita Falls and Northwestern Railroad laid its track in 1910, the community moved west into Roger Mills County to be near the railroad.

Hammon was incorporated on May 22, 1911, and prospered for the next twenty-five to thirty years as a trade center for surrounding ranching and farming communities.

Hammon's first federal census, in 1920, counted 440 residents, and the population rose to 736 by 1930.

The 2020 census counted 479 residents in Hammon, down from 568 in 2010.

In the 2000 census, Hammon had 469 people in 169 households, and almost 40 percent of its residents were American Indian, most of them descendants of Peace Chief Black Kettle's band.

The Dorroh-Trent House in Hammon is listed in the National Register of Historic Places.
