Captain James Hook is the main antagonist of J. M. Barrie's 1904 play Peter Pan; or, the Boy Who Wouldn't Grow Up and its various adaptations, in which he is Peter Pan's archenemy. The character is a pirate captain of the brig Jolly Roger. His two principal fears are the sight of his own blood and the crocodile who pursues him after eating the hand cut off by Pan. An iron hook replaced his severed hand, which gave the pirate his name.

Peter Pan; or, the Boy Who Wouldn't Grow Up, often known simply as Peter Pan, is a work by J. M. Barrie, in the form of a 1904 play and a 1911 novel titled Peter and Wendy, often extended in Peter Pan and Wendy. Both versions tell the story of Peter Pan, a mischievous little boy who can fly, and has many adventures on the island of Neverland that is inhabited by mermaids, fairies, Native Americans, and pirates. The Peter Pan stories also involve the characters Wendy Darling and her two brothers John and Michael, Peter's fairy Tinker Bell, the Lost Boys, and the pirate Captain Hook. The play and novel were inspired by Barrie's friendship with the Llewelyn Davies family.
