Jenolan Caves are limestone caves in the Blue Mountains, New South Wales, Australia, 175 kilometres west of Sydney. They are the most visited of several similar groups in the limestone of the country, and the oldest discovered open caves in the world.

They have many Silurian marine fossils. The calcite formations are sometimes pure white and are know for being very beautiful.
The cave network is very large, with over 40 km of multi-level passages, and the complex is still undergoing active exploration.
Several kilometres of the caves have been rendered accessible to paying visitors and are well lit.
