Harmon County, Administrative county in southwestern Oklahoma, United States.
Harmon County encompasses 539 square miles of land with red soil plains and gypsum formations in the southwestern corner of Oklahoma.
The county received its name from Ohio Governor Judson Harmon when it was established through proclamation by Oklahoma Governor Lee Cruce in 1909.
The county maintains strong agricultural traditions with annual farming events centered around cotton, wheat, and sorghum production in the local communities.
Visitors can access county services and administrative offices at the 1926 courthouse building located in the county seat of Hollis.
The county experienced a territorial dispute resolution in 1930 when the Supreme Court moved the Texas border eastward, reducing its original land area.
