Little Rock is the capital and the most populous city of the U.S. state of Arkansas. It is also the county seat of Pulaski County. It was incorporated on November 7, 1831 on the south bank of the Arkansas River very near the geographic center of the state. The city derives its name from a small rock formation along the river, named "La Petit Roche" by the French in 1799. The capital of the Arkansas Territory was moved to Little Rock from Arkansas Post in 1821. The city's population was 193,524 at the 2010 census.
