Gcwihaba is a cave in Botswana located in Okavango Delta region. The Gcwihaba Caves were part of the Kalahari landscape around 2 million years ago, at least for the entire period of the Pleistocene. The name of the cave is a San word and stands for "hyena's lair". The cave is situated 10 km away from the Namibian border. In 1932 it was first shown to a European, Ghanzi region farmer Martinus Drotsky, and the main cavern was named Drotsky's cavern after him. Gwchihaba is a Botswana National Monument under the Monuments, Relics and Antiquities Act, and has been put forward to become a UNESCO World Heritage Site in 1999. It is the type locality of the mineral gwihabaite (IMA1994-011).
