Temporal range: Late Oligocene
Oreodontoides is an extinct genus of oreodont of the family Merycoidodontidae, subfamily Merycoidodontinae, endemic to North America during the Late Oligocene-Early Miocene subepochs (24.8—20.6 mya), existing for approximately .
Oreodontoides was named by Thorpe (1923) (named as subgenus of Eporeodon by Thorpe in 1921) and raised to genus level. It was synonymized subjectively with Merychyus by Loomis in 1924 and assigned to Merycoidodontidae by Thorpe in 1923 and 1937, (1923), by Schultz and Falkenbach (1947) and Lander (1998).
