The Ofnet Caves (German: Ofnethöhlen) are the remains of an underground karst system on the edge of the Nördlinger Ries in Germany. They are located on a limestone hill near Nördlingen, Bavaria. The caves became famous in 1908 when 33 prehistoric human skulls were discovered. The skulls were dated to the Mesolithic period.
