Eobasileus cornutus is an extinct species of dinocerate mammal.

Eobasileus was 3 m (10 ft) long and stood 1.50 m (5 ft) tall at the shoulder. It looked very similar to the related Uintatherium. Like Uintatherium, it had three pairs of blunt horns on its skull, possibly covered with skin (like the ossicones of a giraffe). The frontal pair may have been composed of keratin, like the horn(s) of a rhinoceros. Eobasileus also had a pair of tusks which were shielded by bony protrusions of the lower jaw.
