Clockwork (also called Clockwork, or All Wound Up) is an illustrated short children's novel by Philip Pullman, first published in the United Kingdom in 1996 by Doubleday. It was first published in the United States by Arthur A. Levine Books in 1998. The Doubleday edition was illustrated by Peter Bailey and the Arthur A. Levine Books edition was illustrated by Leonid Gore. It was shortlisted for the Whitbread Children's Book Award and for a Carnegie Medal in 1997.
Pullman has stated that the novel was inspired by an old clock in London's Science Museum. Inspired by the movement of the clock's gears, he wrote the story with elements that move in opposite directions.
