The following outline provides an overview of and topical guide to natural caves. The word "cave" is loosely defined, but most commonly refers to a natural opening large enough to be entered by a human.[1] These landforms are common around the world, and have even been detected on the Moon and Mars. This outline's scope is limited to these natural formations, specifically excluding the rock-cut features which are often referred to as caves in Eastern Asia.
