Tetrameryx is an extinct genus of the North American artiodactyl family Antilocapridae, known from Mexico,[2] the western United States, and Saskatchewan.[1] The name means "four [horned] ruminant", referring to the division of each horn near its base into two prongs; in T. shuleri, the rear prong is much longer.[3]

One member of the genus, T. shuleri, survived until about 12,000 years ago, and was present when Paleo-Indians reached North America.[4]
