It is located in the northeastern portion of the county, and the population was 511 as of the 2020 census. Jayton's history begins in the 1880s. Originally known as "Jay Flat", it was established 2 miles northeast of its present location and named after a local ranching family. A post office was granted in 1886, and Daniel Jay served as the community's first postmaster. In 1907, the townsite was moved to its present location for improved proximity to rail service, and it was officially renamed "Jayton" later that same year. The community's first newspaper, the Jayton Herald, was established the following year, and the city incorporated in February 1910. By 1925, Jayton was home to 750 residents.
