Deer Cave (Malay: Gua Rusa), located near Miri, Sarawak, Malaysia, is a show cave attraction of Gunung Mulu National Park. It was surveyed in 1961 by G. E. Wilford of the British Borneo Geological Survey, who predicted that Mulu would yield many more caves in the future. The cave, which is also known as Gua Payau or Gua Rusa by the local Penan and Berawan people, is said to have received its name because of the deer that go there to lick salt-bearing rocks and shelter themselves.
