The Geological Society of South Africa (GSSA) is a learned society for geological science that was founded in 1895, making it one of the oldest such societies in Africa. The society was founded by the South African geologist, Dr David Draper. The society annually awards the Draper Memorial Medal in Draper's honour to recognise achievement in geology. They also award the Des Pretorius Memorial Award to recognise exceptional work on economic geology in Africa.
