Nellallitea "Nella" Larsen was an American novelist. Working as a nurse and a librarian, she published two novels, Quicksand (1928) and Passing (1929), and a few short stories. Though her literary output was scant, she earned recognition by her contemporaries.

Passing is a novel by American author Nella Larsen, first published in 1929. Set primarily in the Harlem neighborhood of New York City in the 1920s, the story centers on the reunion of two childhood friends—Clare Kendry and Irene Redfield—and their increasing fascination with each other's lives. The title refers to the practice of "racial passing", which is a key element of the novel. Clare Kendry's attempt to pass as white for her husband, John (Jack) Bellew, is significant and is a catalyst for the tragic events.
