The town of Hallett was founded on December 8, 1904, at the junction of the Arkansas Valley and Western Railway (later the St. Louis and San Francisco Railway) and the Missouri, Kansas and Oklahoma Railroad (later the Missouri, Kansas and Texas Railway). The developer, Hallett Townsite Company, was named for Charles H. Hallett, an officer in the Nineteenth Kansas Cavalry. A post office was established in the town on May 19, 1905, and the first newspaper, the weekly Hallett Herald was published.
Hallett became a trade center for the local agriculture industry. The discovery of Hallett oil field brought a brief boom in 1908 and again in the 1920s. Population peaked at 279 in 1920, then declined to a low of 120 in 1950.
