Quercus crassifolia is a Mexican species of oaks in the beech family. It is widespread from Sonora and Chihuahua to Veracruz and Chiapas.^[3]^[4]^[5] It has also been found in Guatemala.^[6]

Quercus crassifolia is a shrub or small tree sometimes reaching as much as 15 meters in height. The shoots are covered with many yellow or light brown branching hairs. Leaves are broadly egg-shaped with the widest part distant from the stem, up to 20 cm (8 inches) long, with 6-12 pointed teeth on each side. People of the region use the wood to make tool handles and farm implements.^[5]^[7]^[8]^[9]
