Little Rock is the capital and the most populous city of the U.S. state of Arkansas and also the county seat of Pulaski County. Located near the geographic center of Arkansas, Little Rock derives its name from a small rock formation on the south bank of the Arkansas River called la Petite Roche (French: "the little rock"). The "little rock" was used by early river traffic as a landmark and became a well-known river crossing. The city has two major universities that are part of the University of Arkansas System. The campuses of the University of Arkansas at Little Rock and the University of Arkansas for Medical Sciences are located within Little Rock.
