The Moon in the Cloud is a light-hearted children's historical fantasy novel by Rosemary Harris, published by Faber in 1968. It is set in ancient Canaan and Egypt at the time of the Biblical Flood and rooted in the story of Noah's Ark. It is the first book of a series sometimes called the Egyptian trilogy, followed by The Shadow on the Sun (1970) and The Bright and Morning Star (1972). Harris won the annual Carnegie Medal from the Library Association, recognising the year's best children's book by a British subject. Macmillan published the first U.S. edition in 1969.
