The Olympic Theatre, sometimes known as the Royal Olympic Theatre, was a 19th-century London theatre, opened in 1806 and located at the junction of Drury Lane, Wych Street and Newcastle Street. The theatre specialised in comedies throughout much of its existence. Along with three other Victorian theatres, the Olympic was eventually demolished in 1904 to make way for the development of the Aldwych. Newcastle and Wych streets also vanished.

Philip Astley was an English equestrian, circus owner, and inventor, regarded as being the "father of the modern circus". Modern circus, as an integrated entertainment experience that includes music, domesticated animals, acrobats, and clowns, traces its heritage to Astley's Amphitheatre, a riding school that Astley founded in London following the success of trick-riding displays given by him and his wife Patty Jones in 1768. Astley's first competitor was equestrian Charles Hughes, who had previously worked with Astley. Together with Charles Dibdin, a famous author of pantomimes, Hughes opened a rival amphitheatre in London, which Dibdin called the Royal Circus and Equestrian Philharmonic Academy.
