The Sevier Desert is a large arid section of central-west Utah, United States, and is located in the southeast of the Great Basin. It is bordered by deserts north, west, and south; its east border is along the mountain range and valley sequences at the perimeter of the Great Basin, with the large north–south Wasatch Range and its associated mountainous landforms. Its eastern border is specifically, the East Tintic, Gilson, and Canyon Mountains; also the massive Pahvant Range.

The Sevier River is a 400-mile (640 km)-long river in the Great Basin of southwestern Utah in the United States. Originating west of Bryce Canyon National Park, the river flows north through a chain of high farming valleys and steep canyons along the west side of the Sevier Plateau before turning southwest and terminating in the endorheic basin of Sevier Lake in the Sevier Desert. It is used extensively for irrigation along its course, with the consequence that Sevier Lake is usually dry.
