The Hexham wolf (also called the Allendale wolf or the Wolf of Allendale) was a grey wolf that escaped from a zoo and killed livestock in Hexham and Allendale, Northumberland during the winter of 1904. Conflicting reports label it as being either "black and tan" or "dun", although it was largely reported as being large and male. When the Hexham Heads were discovered in 1971, the werewolf sightings that resulted were thought to be the Hexham wolf.
