Robert Kilgore Muchamore is an English author known for his work in young adult fiction. Born on December 26, 1972, in Islington, London, Muchamore has been a significant figure in the young adult literature scene.

He is best known for his series CHERUB, Henderson's Boys, and Rock War. Muchamore's career took a pivotal turn in 2005 with the critically-acclaimed release of Maximum Security. Before his success as an author, he worked as a private investigator.

The inspiration behind the CHERUB series came from his nephew, who lamented the lack of engaging books for his age group. The series' first book, CHERUB: The Recruit, won the Red House Children's Book Award in 2005 in the Older Readers Category.
