Equinae is a subfamily of the family Equidae, known from the Hemingfordian stage of the Early Miocene (16 million years ago) onwards.[1] They originated in North America, before dispersing to every continent except Australia and Antarctica. They are thought to be a monophyletic grouping.[2] Members of the subfamily are referred to as equines; the only extant equines are the horses, asses, and zebras of the genus Equus, with two other genera Haringtonhippus and Hippidion becoming extinct at the beginning of the Holocene, around 11-12,000 years ago.

The subfamily contains two tribes, the Equini and the Hipparionini, as well as two unplaced genera, Merychippus and Scaphohippus. Members of the family ancestrally had three toes, while members of the tribe Equini from the Middle Miocene onwards developed monodactyl feet.[3]
