White Fang is a novel by American author Jack London and the name of the book's eponymous character, a wild wolf-dog. 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.

The story begins before the three-quarters wolf-dog hybrid is born, with two men and their sled dog team on a journey to deliver a coffin to a remote town named Fort McGurry in the higher area of the Yukon Territory, Canada. The men, Bill and Henry, are stalked by a large pack of starving wolves over the course of several days. Finally, after all of their dogs and Bill have been eaten, four more teams find Henry trying to escape from the wolves; the wolf pack scatters when they hear the large group of people coming.

The story then follows the pack, which has been robbed of its last prey. When the pack finally brings down a moose, the famine is ended; they eventually split up, and the story now follows a she-wolf and her mate, One Eye. The she-wolf gives birth to a litter of five cubs by the Mackenzie River, and all but one die from hunger. One Eye is killed by a lynx while trying to rob its den for food for the she-wolf and her cub; his mate later discovers his remains near the lynx's den. The surviving cub and the she-wolf are left to fend for themselves. Shortly afterward, the she-wolf kills all the lynx kittens, prompting the lynx to track her down, and a vicious fight breaks out. The she-wolf eventually kills the lynx but suffers severe injury; the lynx carcass is devoured over a period of seven days.
