Chestnuts (Castanea), including the chinkapins, are a genus of eight or nine species of trees and shrubs in the beech family Fagaceae, native to warm temperate regions of the Northern Hemisphere. The name also refers to the nuts produced by these trees. Most are large trees to 20–40 m tall, but some species (the chinkapins) are smaller, often shrubby.
