White Fang is a novel by American author Jack London and the name of the book's eponymous character a wild wolfdog. First serialized in Outing magazine it was published in 1906. The story details White Fang's journey to domestication in Yukon Territory and the Northwest Territories during the 1890s Klondike Gold Rush. It is a companion novel (and a thematic mirror) to London's best-known work The Call of the Wild (1903) which is about a kidnapped domesticated dog embracing his wild ancestry to survive and thrive in the wild.

Much of White Fang is written from the viewpoint of the titular canine character enabling London to explore how animals view their world and how they view humans. White Fang examines the violent world of wild animals and the equally violent world of humans. The book also explores complex themes including morality and redemption.
