Quercus ajoensis is an uncommon North American shrub with the common name Ajo Mountain scrub oak. It has been found in Arizona and Baja California Sur.[3][4] There are some reports of the species in southern New Mexico, the populations there intergrading with the related Q. toumeyi. Similary, some collections from Utah seem to be intergradations between Q. ajoensis and either Q. turbinella or Q. gambelii.[5]

Quercus ajoensis is a usually a shrub but occasionally attains the stature of small trees up to 3 m (10 feet) tall. Leaves are narrowly egg-shaped, up to 5 cm (2 inches) long, with sharp pointed teeth.[5]

The species is named for the Ajo Mountains in western Pima County, Arizona, southwest of the town of Ajo.[5] The word "ajo" is Spanish for "garlic."
