The Phantom of the Opera is a musical by Andrew Lloyd Webber, lyrics by Charles Hart, additional lyrics by Richard Stilgoe and a libretto by Lloyd Webber and Stilgoe. Based on the novel of the same name by Gaston Leroux, it tells the tragic story of beautiful soprano Christine Daaé, who becomes the obsession of a mysterious but disfigured musical genius living in the subterranean labyrinth beneath the Paris Opéra House.

The musical opened in London's West End in 1986 and on Broadway in New York in 1988, in a production directed by Harold Prince and starring English classical soprano Sarah Brightman (Lloyd Webber's then-wife) as Christine Daaé, screen and stage star Michael Crawford as the Phantom, and international stage performer Steve Barton as Raoul. It won the 1986 Olivier Award and the 1988 Tony Award for Best Musical, with Crawford winning the Olivier and Tony for Best Actor in a Musical. A film adaptation, directed by Joel Schumacher, was released in 2004.

The Phantom of the Opera was the longest running show in Broadway history, and celebrated its 10,000th performance on 11 February 2012, becoming the first Broadway production in history to do so. It is the second longest-running West End musical, after Les Misérables, and the third longest-running West End show overall, after The Mousetrap. With total estimated worldwide gross receipts of over $ 6 billion and total Broadway gross of over $1 billion, The Phantom of the Opera was the most financially successful entertainment event until The Lion King surpassed it in 2014. By 2019, it had been seen by over 140 million people in 183 cities across 41 countries.

The original West End production at His Majesty's Theatre, London, ended its run in 2020, its run cut short by the COVID-19 pandemic. A new production of Phantom opened in the same theatre in July 2021. The original Broadway production played its final performance on 16 April 2023.
