The Eastern Black Rhinoceros (Diceros bicornis michaeli) is also known as the East African Black Rhinoceros. It is a subspecies of the Black Rhino. Its numbers are very low due to poaching for its horn and it is listed as critically endangered.

The Eastern Black Rhino is distinguishable from the southern subspecies as it has a longer, leaner, and more curved horn. Its skin is also very grooved. Diceros bicornis michaeli is also reportedly more aggressive than the other three subspecies of Black Rhino. They are browsers and are usually found in highland forest and savanna habitat.
