Bigfoot, also known as Sasquatch, is an alleged ape-like creature purportedly inhabiting forests, mainly in the Pacific Northwest region of North America. Bigfoot is usually described as a large, hairy, bipedal humanoid.

The scientific community considers Bigfoot to be a combination of folklore, misidentification, and hoaxes, rather than a real creature. In general, mainstream scientific consensus does not support the posited existence of megafauna cryptids such as Bigfoot, because of the improbably large numbers necessary to maintain a breeding population and because climate and food supply issues would make such purported creatures' survival in reported habitats unlikely. Despite these facts, Bigfoot is one of the more famous examples of a cryptid within cryptozoology.
