Cryptozoology refers to the search for animals whose existence has not been proven. This includes looking for living examples of animals that are considered extinct, such as dinosaurs, animals whose existence lacks physical evidence but which appear in myths, legends, or are reported, such as Bigfoot and Chupacabra, and wild animals dramatically outside their normal geographic ranges, such as phantom cats or "ABCs" (an initialism commonly used by cryptozoologists that stands for Alien Big Cats).

The animals cryptozoologists study are often referred to as cryptids, a term coined by John Wall in 1983.

Cryptozoology is not a recognized branch of zoology or a discipline of science. It is an example of pseudoscience because it relies heavily upon anecdotal evidence, stories and alleged sightings.
