Quercus buckleyi, commonly known as Texas red oak or Buckley's oak, is a species of flowering plant in the beech family.[4][5] It is endemic to the southern Great Plains of the United States (Oklahoma and Texas).[6]

Quercus buckleyi is smaller and more likely to be multitrunked than its close relative, the Shumard oak. The two species are interfertile, and hybrids are common along a line from Dallas to San Antonio. Texas red oak usually is 30 to 50 ft (9 to 15 m) tall at maturity, and seldom reaches a height of more than 75 ft (23 m).[7]

Quercus buckleyi was formerly known as Q. texana, but under botanical rules of priority, that name properly refers to Nuttall's oak.[3] This has led to much confusion.[7][8]

Quercus buckleyi is a highly regarded ornamental and shade tree. In autumn, the leaves turn vivid red and orange.
