The Atascosa Mountains is a mountain range in western Santa Cruz County, Arizona, United States. It is sandwiched between the larger Tumacacori Mountains to the north, and a small east–west border range to the south, the Pajarito Mountains; the Pajaritos are on the U.S.–Mexico border and abut the Sierra La Esmeralda range in northern Sonora.
