Kansas City lies in the Midwestern United States, as well as near the geographic center of the country, at the confluence of the longest river in the country, the Missouri River, and the Kansas River (also known as the Kaw River).
The name Kansas City was assigned to distinguish the two. Sitting on Missouri's western border, with downtown near the confluence of the Kansas and Missouri Rivers, the modern city encompasses 316 square miles (820 km 2) in Jackson, Clay, Cass, and Platte counties. It is one of Jackson County 's two county seats (the other being Independence).
