Primrose is a musical in three acts with a book by Guy Bolton and George Grossmith Jr., lyrics by Desmond Carter and Ira Gershwin, and music by George Gershwin. It centres on a writer whose story-within-a-story forms the basis of the plot. It was written expressly for the London stage, where it ran for 255 performances in 1924 and 1925. The musical played in Australia, but it was not performed in the United States until more than half a century after it was written.
