Kansas is a landlocked state in the Midwestern region of the United States. It borders Nebraska to the north, Colorado to the west, Oklahoma to the south, and Missouri to the east. Kansas is named after the Kansas River, in turn named after the Kansa people. Its capital is Topeka, and its most populous city is Wichita; however, the largest urban area is the bi-state Kansas City metropolitan area surrounding Kansas City, Missouri, which straddles the border of Kansas and Missouri.
