Dinnetherium is an extinct genus of mammaliaforms from the Early Jurassic of Arizona. The type species, D. nezorum, was named in 1983. It was discovered in a Sinemurian layer of the Kayenta Formation, within the Gold Spring Quarry 1. The holotype is MNA V3221, which is a partial right mandible.
Dinnetherium has sometimes been placed in the family Megazostrodontidae, but in 2011 the monotypic family Dinnetheriidae and order Dinnetheria were erected for the genus.
