Plum Bun: A Novel Without a Moral is a novel by Jessie Redmon Fauset first published in 1928. Written by an African-American woman who, during the 1920s, was the literary editor of The Crisis, it is often seen as an important contribution to the Harlem Renaissance.

Overtly conventional through its employment of elements and techniques of traditional genres such as the romance or the fairy tale, Plum Bun at the same time transgresses these genres by its depiction, and critique, of racism, sexism and capitalism. The heroine, a young, light-skinned African-American woman called Angela Murray, leaves behind her past and passes for white in order to be able to attain fulfilment in life. Only after she has lived among white Americans does she find out that crossing the racial barrier is not enough for a woman like herself to realize her full potential. The detailed description of her coming of age makes Plum Bun a classic Bildungsroman.
