Bigfoot, also commonly referred to as Sasquatch (ˈsæskwætʃ or ˈsæskwɒtʃ), is a large and hairy human-like mythical creature purported to inhabit forests in North America, particularly in the Pacific Northwest.
Enthusiasts of the subject have offered various forms of dubious evidence to prove Bigfoot's existence, including anecdotal claims of sightings, as well as alleged photographs, video and audio recordings, hair samples, and casts of large footprints. Most of this evidence has since been identified as hoaxes or misidentification, and the majority of scientists do not find any of the remaining evidence compelling.
Tales of wild, hair-covered humanoids exist throughout the world, and such creatures appear in the folklore of North America, including the mythologies of indigenous people. Bigfoot is an enduring element of popular culture and an icon within the pseudoscience and subculture of cryptozoology.
Most scientists have historically discounted the existence of Bigfoot, considering it to be the result of a combination of folklore, misidentification, and hoax, rather than a living animal. Folklorists trace the phenomenon of Bigfoot to a combination of factors and sources, including indigenous cultures, the European wild man figure, and folk tales. Wishful thinking, a cultural increase in environmental concerns, and overall societal awareness of the subject have been cited as additional factors.
Other creatures of relatively similar descriptions are alleged to inhabit various regions throughout the world, such as the Skunk ape of the southeastern United States, the Almas, Yeren, and Yeti in Asia, and the Australian Yowie, all of which are also engrained in the cultures of their regions.
Bigfoot is often described as a large, muscular, and bipedal ape or human-like creature covered in black, dark brown, or dark reddish hair. Anecdotal descriptions estimate a height of roughly , with some descriptions having the creatures standing as tall as . Some alleged observations describe Bigfoot as more human than ape, particularly in regards to the face.
