About Stephens County Free Fair

The Stephens County Free Fair in Duncan is an August fair in the oil and cattle country of southwest Oklahoma, celebrating the petroleum and ranching heritage of a county defined by the Halliburton Company's founding in Duncan and the rolling red hills of the Wichita Mountains outliers.

What to Expect

Expect livestock shows, FFA and 4-H competitions, carnival rides, local food vendors, and a fair serving the oil industry workers and ranching families of Stephens County.

Visitor Tips

Duncan is a significant Oklahoma oil city — the Chisholm Trail Heritage Center (a world-class museum dedicated to the Chisholm Trail cattle drives that passed through this area), the Stephens County Historical Museum, and the rolling red plains of southwest Oklahoma make Duncan an informative stop in the heart of Comanche country.
