Littlefield is an unincorporated community in Mohave County located in the Arizona Strip region of the U.S. state of Arizona. It is located along Interstate 15 approximately 10 miles northeast of Mesquite, Nevada. Littlefield is located in the 86432 zip code, which had a population of 1,053 as of the 2000 census. Littlefield was first settled by Latter-day Saints in 1865. Littlefield is home to the Littlefield Unified School District, the geographically largest school district in Arizona. Littlefield and neighboring Beaver Dam have the distinction of being the only towns in Arizona along I-15. Owing to its location in the Arizona Strip, northwest of Grand Canyon National Park and west of the Virgin River, it is essentially isolated from the rest of the state. Travel to other towns within Arizona requires crossing through either Nevada or Utah, or by routing through unpaved roads to the rest of Arizona's road network. The Virgin River Gorge is located just to the east of Littlefield.
