History
Following an election on May 22, 1909, Harmon County was created by proclamation of Governor Lee Cruce on June 2. Carved from adjacent Greer County, the new county was named in honor of Judson Harmon, who was Governor of Ohio at the time. The area now covered by Harmon County had been a part of Texas until the U. S. Supreme Court awarded it to Oklahoma Territory in 1896.

Another election held September 1, 1909, confirmed Hollis as the county seat. There were two other contestants: the towns of Harmon and Rosser. County offices operated in rented space until a courthouse was built in Hollis in 1926. In 1930, the U.S. Supreme Court ruled that the boundary between Texas and Oklahoma was actually 3800 ft farther east than originally believed. It returned the disputed land to Texas, reducing the county's area to its present size.

A railroad built from Altus, Oklahoma to the Texas state line came to Hollis and Gould in 1910. The line was built by the Altus, Wichita Falls and Hollis Railway (later acquired by the Missouri, Kansas and Texas Railroad).
