Hypertragulidae is an extinct family of Paleogene ruminants endemic to North America from the Eocene until the Oligocene.

Instead, the chevrotains are probably the closest living relatives to these ancient deer-like animals.

Hypertragulidae was named by Edward Drinker Cope and considered paraphyletic by W. D. Matthew.

It was assigned to Ruminantia by Matthew and William King Gregory; to Pecora by H.J.

[citation needed] They ranged in body mass from as small as 2.16 kg (4.8 lb) with Parvitragulus to as large as 4.24 kg (9.3 lb) in Hypisodus.
