Adinotherium (meaning "not Deinotherium")^[2] is an extinct genus of Toxodontidae, large bodied hoofed ungulates which inhabited South America during the Miocene living from 17.5—11.61 Ma and existed for approximately 5.89 million years.^[3]

The 1.5 metres (4.9 ft) long animal looked like a smaller version of its rhinoceros-like relative Toxodon. Its front legs were somewhat longer than those of its relatives, making its hip and shoulder height about equal. A small horn atop Adinotherium's skull may have played a role in the mating season.^[4]
