This is a list of karst features in Western Australia. It includes all named features that occur in the Australian Speleological Federation Karst Index Database (KID).^[1] The term "karst feature" is an umbrella term for topographical features formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. While the majority of features in the list below refer to cave entrances, some other features include cliffs, gorges and a calcified wooden water wheel.

Each feature is given a unique identification number, and many are also given a name. This list is restricted to named features. For conservation reasons, the precise locations of features are not made available to the public. However, most features are allocated to an area.

The list shows karst features (e.g. a cave entrance), not cave systems, so caves with 2 or more entrance points will appear multiple times in the list.
