Addie Pray (1971) is a novel by Joe David Brown. It was the basis for the movie Paper Moon (1973) directed by Peter Bogdanovich. The novel was re-printed in 2002 as a paperback with the title Paper Moon: A Novel.

The novel is narrated by Addie, an orphaned girl, who travels with confidence man "Long Boy" Moses Pray in the early 1930s, during the Great Depression. Their travels are mainly in the State of Alabama, but they do go elsewhere on occasion. The second half of the novel takes place in and around New Orleans, where Addie and Mose become involved in a scam with confidence man Colonel Culpepper. This portion of the tale would be omitted from the film Paper Moon.

Addie states at the beginning of the novel that Long Boy may or may not be her father; she says that her late mother was the "wildest" girl in her town, and that Long Boy is one of her three possible fathers. The book features three scams not depicted in the movie, including bilking cotton dealers, investors in a worthless mine, and a wealthy lawyer in New Orleans.
