Quercus coccinea, the scarlet oak, is an oak in the red oak section Quercus sect. Lobatae. The scarlet oak can be mistaken for the pin oak, the black oak, or occasionally the red oak. On scarlet oak the sinuses between lobes are "C"-shaped in comparison to pin oak (Q. palustris), which has "U"-shaped sinuses and the acorns are half covered by a deep cap.
Scarlet oak is found from southwestern Maine west to New York, Ohio, southern Michigan, and Indiana; south to southern Illinois, southeastern Missouri, and central Mississippi; east to southern Alabama and southwestern Georgia; and north along the western edge of the Coastal Plain to Virginia.
