The Scarlet Pimpernel is a musical with music by Frank Wildhorn and lyrics and book by Nan Knighton, based on the 1905 novel of the same name by Baroness Orczy. The show is set in England and France during the Reign of Terror of the French Revolution. The story is a precursor to the spy fiction and the superhero genres, where a hero hides under a mild-mannered alias.

The Scarlet Pimpernel is the first novel in a series of historical fiction by Baroness Orczy, published in 1905. It was written after her stage play of the same title enjoyed a long run in London, having opened in Nottingham in 1903.
