The Sedgwick County Fair has been held in Cheney, Sedgwick County, Kansas, United States since 1940. Floyd Souders (see also Souders Historical Museum), a citizen of Cheney began working on having a county fair in the community in 1939. Even though Cheney was one of the smaller towns in the county, it had been successful in hosting a Fall Festival, and Souders thought Cheney would be a good site for a county fair.
