The Werewolf of Fever Swamp is the fourteenth book in the original Goosebumps, the series of children's horror fiction novellas created and authored by R. L. Stine.

The book was well received by critics, and was featured on the USA Today and Publishers Weekly bestseller list.

Cassie O'Rourke, a girl who lives in the neighborhood, suggests that a werewolf is the reason for Mr. Warner's disappearance.

That night, Grady hears howling and observes Wolf slowly moving towards the swamp shortly afterward.

The Werewolf of Fever Swamp was first published in December 1993 by Scholastic, and reissued in October 2009 under the Classic Goosebumps rename.
