The West African black rhinoceros (Diceros bicornis longipes) was a subspecies of the black rhino that was declared extinct in 2011.

The subspecies last existed in Cameroon, but an extensive survey in 2006 did not find any signs of living West African black rhinos. According to the IUCN, "it is highly probable that this subspecies is now extinct" thanks to increased poaching and demand for rhino horn.
