Burlesque is a literary, dramatic or musical work intended to cause laughter by caricaturing the manner or spirit of serious works, or by ludicrous treatment of their subjects. The word derives from the Italian burlesco, which itself derives from the Italian burla – a joke, ridicule or mockery.

Burlesque overlaps in meaning with caricature, parody and travesty, and, in its theatrical sense, with extravaganza, as presented during the Victorian era. "Burlesque" has been used in English in this literary and theatrical sense since the late 17th century. It has been applied retrospectively to works of Chaucer and Shakespeare and to the Graeco-Roman classics. Contrasting examples of literary burlesque are Alexander Pope's sly The Rape of the Lock and Samuel Butler's irreverent Hudibras. An example of musical burlesque is Richard Strauss's 1890 Burleske for piano and orchestra. Examples of theatrical burlesques include W. S. Gilbert's Robert the Devil and the A. C. Torr – Meyer Lutz shows, including Ruy Blas and the Blasé Roué.
