Emory oak (Quercus emoryi) is a species of oak common in Arizona, New Mexico and western Texas (Big Bend National Park), USA, and northern Mexico south to Durango and San Luis Potosí. It typically grows in dry hills at moderate altitudes.
It is a live oak in the red oak group, retaining its leaves through the winter until the new leaves are produced in spring, and is a large shrub or small tree from 5-17 m tall. The leaves are 3-6 cm long, entire or wavy-toothed, leathery, dark green above, paler below. The acorns are 1.5-2 cm long, blackish-brown, and mature in 6-8 months from pollination; the kernel is sweet, and is an important food for many mammals and birds.
The tree is named after the United States army surveyor, Lieutenant William Hemsley Emory, who surveyed the area of west Texas where it was discovered in 1846.
