Jonathan Anthony Stroud (born 27 October 1970) is a British writer of fantasy fiction, best known for the Bartimaeus young adult sequence and Lockwood & Co. children's series.

His books are typically set in an alternative history London with fantasy elements, and have received note for his satire, and use of magic to reflect themes of class struggle.

By narrating the story from the perspective of Bartimaeus, a sarcastic and slightly egomaniacal djinni, Stroud examines the stereotypes and ethics of the magician class and the enslaved demons.

A third novel, titled The Hollow Boy, was announced through a competition orchestrated by Stroud, asking readers to send in an idea for a ghost to feature in the third story.
