Run, River is the debut novel of Joan Didion, first published in 1963.

[2] In her 2003 book of essays Where I Was From, Didion turned a critical eye on this novel, calling the novel's nostalgia ''pernicious''.

[3] She recalled writing it as a homesick girl lately moved from California to New York, and judged it to be a work of false nostalgia, the construction of an idyllic myth of rural Californian life that she knew never to have existed.

In a 1978 interview, Didion said that she had intended the title to be Run River but that the English publisher, Jonathan Cape, inserted a comma; "but it wasn't of very much interest to me because I hated it both ways.

The working title was In the Night Season", which her American publisher did not like.
