The Edge of the Cloud is a 1969 historical novel written for children or young adults by K. M. Peyton. It was the second book in Peyton's original Flambards trilogy, comprising three books published by Oxford with illustrations by Victor Ambrus (1967 to 1969), a series the author extended more than a decade later. Set in England prior to the First World War, it continues the romance of Christina Parsons and Will Russell. The title alludes to Will's participation in early aviation.

Peyton won the annual Carnegie Medal from the Library Association, recognising the year's best children's book by a British subject.
