The chinkapin oak (Quercus muehlenbergii) is an oak in the white oak group (Quercus sect. Quercus). The name is also spelled chinquapin oak. It is native to eastern North America, from Vermont and southern Ontario west to Iowa, south to northwest Florida and eastern Texas, with disjunct populations in west Texas and southeast New Mexico, and eastern Mexico from Coahuila south to Hidalgo. It is occasionally seen outside its native range with examples at Ottawa, Ontario, Canada, Raleigh, North Carolina and Lake Worth, Florida.
It is a deciduous tree reaching 30 m tall (exceptionally up to 50 m), with a rounded crown and thin, scaly or flaky bark on the trunk. The name comes from the resemblance of the leaves to those of a chestnut or chinquapin, although they also greatly resemble the chestnut oak or swamp chestnut oak; coarsely toothed, 5–15 cm long and 4–8 cm broad. The acorns are 1.5–2 cm long, and mature in about 6 months after pollination.
The scientific name honors Gotthilf Heinrich Ernst Muhlenberg (1753–1815), a Lutheran pastor and amateur botanist in Pennsylvania. Because the name may be spelled "Mühlenberg" with an umlaut over the "u", the scientific name is commonly spelled muehlenbergii.
The leaf base is typically more rounded.
The veins and sinuses are regular.
Acorns on short stalks and turn chestnut brown in the fall.
The leafs have sharp teeth but no bristles- member of the white oak subgenus.
