Quercus turbinella has been found in Arizona, New Mexico, Colorado, Utah, Nevada, southern California, and western Texas, as well as Baja California. In California, it occurs in the New York mountains and a few eastern California desert ranges. The populations on the desert mountains in the western Mojave desert and the inner coastal ranges are now considered Quercus john-tuckeri. It grows in woodland, chaparral, forest, and other habitat. It is most common in chaparral habitat in central Arizona, through the transition zone of the Mogollon Rim White Mountains, but also southeast Arizona in the Madrean Sky Island mountain ranges of sky islands.
Quercus turbinella easily hybridizes with other oak species, including Quercus gambelii, Q. havardii, Q. arizonica, and Q. grisea. Many species of animals use it for food, with wild and domesticated ungulates browsing the foliage and many birds and mammals eating the acorns. Animals also use the shrub as cover, and mountain lions hide their kills in the thickets. (contributed by Mary Ann Machi)
