The Subtle Knife is a young-adult fantasy novel published in 1997 and the second book in Philip Pullman's His Dark Materials trilogy. The novel continues the adventures of Lyra Belacqua (now known as Lyra Silvertongue) recounted in the first novel, Northern Lights, as she investigates the mysterious phenomenon of Dust. Will Parry is introduced as a companion to Lyra, and together they explore new worlds in the search for Will's father.

From 2019 to 2020, the novel was adapted as the first and second series of the joint BBC-HBO television series His Dark Materials, the former series additionally adapting Northern Lights.
