The Rocky Horror Show is a musical with music, lyrics and book by Richard O'Brien. A humorous tribute to various B movies associated with the science fiction and horror genres from the 1930s to the early 1960s, the musical tells the story of a newly engaged couple getting caught in a storm and coming to the home of a mad transvestite scientist, Dr Frank-N-Furter, unveiling his new creation, Rocky, a sort of Frankenstein-style monster in the form of an artificially made, fully grown, physically perfect muscle man.

The show was produced and directed by Jim Sharman. The original London production of the musical was premiered at the Royal Court Theatre (Upstairs) on 19 June 1973 (after two previews on 16 and 18 June 1973). It later moved to several other locations in London and closed on 13 September 1980. The show ran for a total of 2,960 performances in London and won the 1973 Evening Standard Theatre Award for Best Musical. Songs in the musical include "Time Warp" and "Sweet Transvestite" (co-written by O'Brien and Richard Hartley), while the costumes were designed by Sue Blane. Its 1974 debut in the US in Los Angeles had a successful nine-month run, but its 1975 Broadway debut at the Belasco Theatre lasted only three previews and forty-five showings, despite earning one Tony nomination and three Drama Desk nominations. Various international productions have since spanned across six continents as well as West End and Broadway revivals and eight UK tours. In 1991 it was nominated for the Laurence Olivier Award for Best Musical Revival. Actor Tim Curry, who originated the role of Dr. Frank-N-Furter, became particularly associated with the musical.

The musical was adapted into the 1975 film The Rocky Horror Picture Show, starring O'Brien as Riff Raff, with Curry also reprising his role; the film has the longest-running release in film history. In 2016, it was adapted into the television film The Rocky Horror Picture Show: Let's Do the Time Warp Again. The musical was ranked eighth in a BBC Radio 2 listener poll of the "Nation's Number One Essential Musicals", and it was one of eight British musicals featured on a commemorative stamp issued by the Royal Mail in 2011.^[1]

Beyond its cult status, The Rocky Horror Show is also widely said to have been an influence on countercultural and sexual liberation movements that followed on from the 1960s. It was one of the first popular musicals to depict fluid sexuality during a time of division between generations and a lack of sexual difference acceptance. Like the film adaptation, the musical is noted for a long-running tradition of audience participation through call-back lines and attending dressed up as characters from the show.^[2] On the 50th anniversary of the musical in 2023, BBC News states that since debuting in London in 1973 the "production has been performed in 20 different languages" and been "seen by 30 million people globally".^[2]
