The Duncan Swap Meet is conveniently located in the heart of the US in southwest Oklahoma. There is a strong muscle car and antique car tradition in the area, with many car clubs and enthusiasts.

​

Oklahomans are "can-do" people - they find old cars and parts to either rebuild or take to swap meets for others to complete a project. The moderate climate and minimal use of road salt helps local vehicles stay rust-free.

The Duncan Swap Meet is held at the Stephens County Fairgrounds. This wonderful facility was recently expanded and has 140,000 plus square feet under roof and 42 acres of grounds. Sixty-five RV hook-ups are available on the grounds, with a dump station included. Many flush toilets are located in the fairgrounds buildings. Showers are also available. The fair staff works hard to keep the facility clean and neat. They are very experienced with large crowds for conventions and shows.
