Theroteinus is an extinct genus of haramiyidan mammaliaforms from the Late Triassic of France and Britain.

It contains three species: T. nikolai, T. rosieriensis and T. jenkinsi, the former two of which are known exclusively from teeth found at the sand quarry of Saint-Nicolas-de-Port,[1][2] while T. jenkinsi is known from a bedded sequence belonging to the Westbury Formation in a road cutting near Holwell, Dorset.

[3] Theroteinus is the only member of the family Theroteinidae and the suborder Theroteinida.
