The Tinajas Altas Mountains is an arid northwest-southeast trending mountain range in southwestern Arizona in the southwestern Sonoran Desert. It is essentially a lower elevation extension of the Gila Mountains (Yuma County) adjacent, and northwest. About ten miles of the range is in Arizona; the southern twenty miles extends into Sonora, Mexico. This mountain range is amongst an eleven mountain sequence of trending ranges and valleys in the hottest region of the southwest Sonoran Desert. This southwestern Arizona region is on the northern perimeter of the Gran Desierto de Altar-(part of the Pinacate volcanic field, and region containing the biosphere reserve, called the Pinacate Reserve).

The Tinajas Altas Mountains lie southeast of Yuma, Arizona and east of the Yuma Desert; the Lechuguilla Desert borders the mountains on the east; a low-elevation minor range, the Butler Mountains lie to the west. The Tinajas Altas lie in the western portion of the Barry M. Goldwater Air Force Range which is used by the MCAS, the Marine Corps Air Station, Yuma.

The closest community to the Tinajas Altas Mountains is Fortuna Foothills in the east of the Yuma Valley adjacent to the Gila Mountains.
