She and Allan is a novel by H. Rider Haggard, first published in 1921. It brought together his two most popular characters, Ayesha from his 1887 novel She (to which it serves as a prequel), and Allan Quatermain from his 1885 novel King Solomon's Mines. Umslopogaas from Nada the Lily (1892) also appears in the novel as a major character. Along with the other three novels in the Ayesha series, She and Allan was adapted into the 1935 film She. She and Allan is the third story in the Ayesha series and the fifteenth in the Quatermain series. It was republished by the Newcastle Publishing Company as the sixth volume of the Newcastle Forgotten Fantasy Library series in September 1975.
