The Las Vegas Valley is a major metropolitan area located in the southern part of the U.S. state of Nevada. The largest urban agglomeration in the state, it is the heart of the Las Vegas–Paradise-Henderson, NV MSA. The Valley is largely defined by the Las Vegas Valley landform, a  basin area surrounded by mountains to the north, south, east and west of the metropolitan area. The Valley is home to the three largest incorporated cities in Nevada: Las Vegas, Henderson and North Las Vegas. Six unincorporated towns governed by the Clark County government are part of the Las Vegas Township and constitute the largest community in the state of Nevada.
