Arkansas is a state located in the southern region of the United States of America. Arkansas shares a border with six states, with its eastern border largely defined by the Mississippi River. Its diverse geography ranges from the mountainous regions of the Ozarks and the Ouachita Mountains, which make up the U.S. Interior Highlands, to the eastern lowlands along the Mississippi River. The capital and most populous city is Little Rock, located in the central portion of the state.
The name Arkansas is a French pronunciation of a Quapaw word meaning "land of downriver people". The pronunciation "arkansaw" was made official by an act of the state legislature in 1881.
The Little Rock-North Little Rock-Pine Bluff Combined Statistical Area had 829,032 people in the 2006 census estimates and is the largest in Arkansas.
