Mat Saltbush is one of several woody species in the genus Atriplex that can be found in Utah but its range is restricted to the southeastern third of the state that lies within the Colorado Plateau (including the Uinta Basin) to which it is endemic. In Utah, this species can be found in Carbon, Duchesne, Emery, Garfield, Grand, Kane, San Juan, Sevier, Uintah, and Wayne counties. This species' range also extends into Colorado (Delta, Mesa, Moffat, Montezuma, and Montrose counties) and New Mexico (San Juan County).

One place where this plant is unavoidably ubiquitous is along U.S. Highway 191 in Emery County, Utah between the ghost town of Woodside and Interstate 70 and Green River (the city) where it grows in salt flats and in some places is the only plant found growing there. Some other plants that it sometimes grows with that I recognized include Globemallow (Sphaeralcea), Porcupine Pricklypear (Opuntia polyacantha var. hystricina), Black Greasewood (Sarcobatus vermiculatus), and Astragaluses (Astragalus).
