"Tooth and Claw" is the second episode of the second series of the British science fiction television series Doctor Who, which was first broadcast on BBC One on 22 April 2006.

The episode is set in Scotland in 1879. In the episode, a group of warrior monks intend to use an alien werewolf (Tom Smith) to take over the British Empire and start an "Empire of the Wolf" by turning Queen Victoria (Pauline Collins) into a werewolf.

This was also the first episode of Series 2 to include mention of "Torchwood", the reocurring mystery box arc of Series 2. This episode also establishes the origins of the Torchwood Institute, which was founded as a secret organisation in 1879 by Queen Victoria to investigate and fight extra-terrestrial threats, including the Doctor, within Britain after her encounter with the Werewolf.
