Knoxville is a city in the U.S. state of Tennessee, and the county seat of Knox County. It is the state's third largest city after Nashville and Memphis. Knoxville is the principal city of the Knoxville Metropolitan Statistical Area.
Knoxville is the home of the flagship campus of the University of Tennessee, whose sports teams, called the "Volunteers" or "Vols," are extremely popular in the surrounding area. Knoxville is also home to the headquarters of the Tennessee Valley Authority, the Tennessee Supreme Court's courthouse for East Tennessee, and the corporate headquarters of several national and regional companies. As one of the largest cities in the Appalachian region, Knoxville has positioned itself in recent years as a repository of Appalachian culture, and is one of the gateways to the Great Smoky Mountains National Park.
Knoxville is roughly divided into the Downtown area and sections based on the four cardinal directions: North Knoxville, South Knoxville, East Knoxville, and West Knoxville. Downtown Knoxville traditionally consists of the area bounded by the river on the south, First Creek on the east, Second Creek on the west, and the railroad tracks on the north, though the definition has expanded to include the U.T. campus and Fort Sanders neighbourhood, and several neighbourhoods along or just off Broadway south of Sharp's Ridge ("Downtown North"). While primarily home to the city's central business district and municipal offices, the Old City and Gay Street are mixed residential and commercial areas.
