The Hippocastanaceae is a small family, with the most widespread genus Aesculus (the horsechestnuts), which today is taken to include Pavia (the buckeyes). However, the American genus Billia and the Chinese genus Handeliodendron should also be members of the family. A feature of the family is the palmate compound leaves.

The family is closely related to the large, mostly tropical family Sapindaceae, and these days it is common for both Aceraceae and Hippocastanaceae to be included in the Sapindaceae s.l. Best evidence so far shows each of these two smaller families to be monophyletic (i.e. they are "good" groups) and to be basal to Sapindaceae. Inclusion (or not) is a matter of taxonomic opinion, rather than of hard fact.
