Oromerycidae is a small (both in size and diversity), extinct family of artiodactyls (even-toed hoofed mammals) closely related to living camels, known from the middle to late Eocene of western North America. Oromerycids are placed in the artiodactyl suborder Tylopoda, which also includes camels and a variable number of extinct families. Some researchers have viewed the similarity to camels as strong enough to warrant placement of oromerycids within the family Camelidae as a subfamily, Oromerycinae, but most have favored placement in a distinct family, albeit a closely related one.
