"It Ain't Gonna Rain No Mo'" or "It Ain't Gonna Rain No More" is a folk song first recorded in 1923 by "The Red-Headed Music Maker," the singer and instrumentalist Wendell Hall (1896–1969).

[2] The recording was a hit in the US and also in Britain, where it was sung during the 1925 FA Cup final by Sheffield United supporters, making it a popular football song of the era.

Carl Sandburg suggested that the song goes back at least to the 1870s, and includes verses in his American Songbag (1927).

[1] The song may be somewhat familiar to modern listeners because of its use in a number of films, especially vintage animated cartoons, typically in the form of a brief vocal refrain, or as an instrumental musical comment.

[3] This tradition has continued into modern times: a part of the song was sung in the 2014 film Against the Sun and was also featured over the end credits.
