Seymour, the county seat of Baylor County, is at the intersection of US highways 82, 183, 283, and 277 and Farm roads 422 and 1919, southwest of Wichita Falls toward Munday. Earlier, Seymour was situated where the Western Trail crossed the Brazos River. It was settled by pioneers from Oregon who called the place Oregon City.
In 1990 the population was estimated at 3,185. At that time Seymour was primarily an agribusiness and legal center, rather than an oil industry center; the town also drew some tourists who visited nearby Lake Kemp. Clothing and metalworks were manufactured in Seymour, and cotton, grains, and cattle were the most important local products. Fish Day in May has been an important local event since the 1920s. The Old Settlers Reunion and Rodeo held each July originated in 1896 as the Cowboy Reunion.
