The Pajarito Mountains are a small mountain range of western Santa Cruz County, Arizona. The range is adjacent the Atascosa Mountains at its north, with both ranges in the center of a north-south sequence of ranges called the Tumacacori Highlands. The Highlands have the Tumacacori Mountains at the north, and south of the U.S.-Mexico border, the Sierra La Esmeralda range, (the Emerald Mountains). The Tumacacori Highlands are part of a regional conservancy study of 'travel corridors' for cats, called Cuatros Gatos, Four Cats, for mountain lions, ocelot, bobcat, and jaguar.
The lower elevation Cerro Colorado Mountains to the northwest, and the San Luis Mountains, west are also part of the Highlands region. At the west of the Pajarito's and adjacent to the San Luis range, and Cobre Ridge peaks, is the Pajarito Wilderness. East of the Highlands is the Santa Cruz River Valley corridor.
