The tree species Aesculus glabra is commonly known as Ohio buckeye, American buckeye, or ' fetid buckeye'. Glabra is one of 13–19 species of Aesculus also called horse chestnuts.

It is native primarily to the Midwestern and lower Great Plains regions of the United States, extending southeast into the Nashville Basin. It is also found locally in the extreme southwest of Ontario, on Walpole Island in Lake St. Clair, and in isolated but large populations in the South ( Adams County, Mississippi). It is a medium-sized deciduous tree growing to tall.

The leaves are palmately compound with five (rarely seven) leaflets, long and broad. The flowers are produced in panicles in spring, yellow to yellow-green, each flower long with the stamens longer than the petals (unlike the related yellow buckeye, where the stamens are shorter than the petals). The fruit is a round or oblong spiny capsule diameter, containing 1 to 3 nut-like seeds, in diameter, brown with a whitish basal scar.

The foliage and fruits contain tannic acid, and are poisonous to cattle and humans.
