The Edinburgh Festival Theatre is a performing arts venue located on Nicolson Street in Edinburgh Scotland used primarily for performances of opera and ballet, large-scale musical events, and touring groups. After its most recent renovation in 1994, it seats 1,915. It is one of the major venues of the annual summer Edinburgh International Festival and is the Edinburgh venue for the Scottish Opera and the Scottish Ballet.

The present theatre’s location is Edinburgh’s longest continuous theatre site, for there has been a theatre in that location since 1830. From being Dunedin Hall, the Royal Amphitheatre, Alhambra Music Hall, the Queen’s Theatre, Pablo Fanque's Amphitheatre, and Newsome’s Circus, the site became the Empire Palace Theatre, the first of the famous Moss Empires’ chain, opening on 7 November 1892. Designed by the great British theatre architect, Frank Matcham, (who built the London Coliseum, among others) its décor was lavish, with elephants with Nubian riders, nymphs and cherubs in abundance on the plasterwork, and it seated 3000 people on four levels.

For the following twenty years all the top artists of the day played at the Empire Palace until, on 9 May 1911, there was a disastrous fire on stage. While all 3000 theatre goers escaped safely (there were eleven backstage deaths), the theatre re-opened three months later. However, given the long term competition from the growth of film as a popular medium, the theatre was re-equipped to present bigger and more spectacular shows. Reusing some of Matcham’s original design concepts, the theatre re-opened on 1 October 1928 with the musical Show Boat.

Between 1928 and 1963 the Empire was a variety, musical and opera house, often including ice shows. Big names like Harry Lauder, Charles Laughton, Fats Waller, Joe Loss, and Laurel and Hardy appeared, while English comedians Max Wall, Morecambe and Wise and Harry Worth established themselves at the Empire.

In addition to the music hall and popular entertainers who appeared at the Empire, the theatre became a principal venue of the Edinburgh International Festival between 1947 and 1963. It was particularly associated with international ballet and, during the first Festival in 1947, Margot Fonteyn danced in The Sleeping Beauty, while in subsequent years, performances by the Old Vic theatre company, the Royal Ballet and the Royal Opera were presented.

However, for nearly thirty years after 1963 the theatre became a bingo hall, only temporarily serving as a Festival venue. Finally, after its third major re-modeling, the Empire Palace Theatre re-opened in June 1994 with a glass-fronted structure for the new entrance (created by architect Colin Ross), as the now-renamed Edinburgh Festival Theatre. In 1997, the distinguished theatre manager and artistic director Stephen Barry was appointed to shape the rejuvenated venue's future. With the restoration of the Empire Theatre’s former 1928 glory, plus a dramatic mix of art nouveau, beaux arts and neo-classicism, and including adequate acoustics, the new theatre serves all the artistic needs of the community.

The theatre is said to be haunted by a tall, dark stranger rumoured to be the famous illusionist Sigmund Neuberger, aka The Great Lafayette, who was one of those who burned to death in the fire at the Empire in 1911.
