Trigodon is an extinct genus of the family Toxodontidae, a large bodied notoungulate which inhabited South America during the Late Miocene to Early Pliocene (Mayoan to Montehermosan in the SALMA classification), living from 11.61--4.0 Ma and existed for approximately 7.61 million years. The type species is T. gaudryi.
It bore a superficial resemblance to a rhinoceros, in that it had a horn on its forehead.
