The Laramie Plains is an arid highland (approximately elevation 8000 ft) in south central Wyoming in the United States. The plains extend along the upper basin of the Laramie River on the east side of the Medicine Bow Range. The city of Laramie is the largest community in the valley. The plains are separated from the Great Plains to the east by the Laramie Mountains, spur of the Front Range that extends northward from Larimer County, Colorado west of Cheyenne. The high altitude of the plains makes for a cold climate and relatively short growing season.
