Buckeye is the name given to trees and shrubs of the genus Aesculus. These woody plants have opposite, palmately divided leaves. The most familiar member of the genus worldwide is the horsechestnut, Aesculus hippocastanum, formerly put in its own genus, Hippocastanum but now usually included in Aesculus.

Buckeyes are poisonous, but some native American tribes leached the pulverized nuts to make them edible.

Several members of the genus are used as ornamentals. The horsechestnut, red buckeye, bottlebrush buckeye, and painted buckeye are all planted for their showy flowers. Several showy horticultural hybrids have been developed.

The Ohio buckeye is the state tree of Ohio.
