Potoroo is a common name for species of Potorous, a genus of smaller marsupials. They are allied to the Macropodiformes, the suborder of kangaroo, wallaby, and other rat-kangaroo genera. All three extant species are threatened by ecological changes since the colonisation of Australia, especially the long-footed potoroo Potorous longipes (endangered) and P. gilbertii (critically endangered). The broad-faced potoroo P. platyops disappeared after its first description in the 19th century. The main threats are predation by introduced species (especially foxes) and habitat loss.
