The Alhambra was a popular theatre and music hall located on the east side of Leicester Square, in the West End of London. It was built originally as the Royal Panopticon of Science and Arts opening on 18 March 1854. It was closed after two years and reopened as the Alhambra. The building was demolished in 1936. The name was also adopted by many other British music hall theatres located elsewhere; in Bradford, in Hull and in Glasgow etc. The name comes from association with the Moorish splendour of the Alhambra palace in Granada, Spain.

Music hall is a type of British theatrical entertainment that was most popular from the early Victorian era, beginning around 1850, through the Great War. It faded away after 1918 as the halls rebranded their entertainment as variety. Perceptions of a distinction in Britain between bold and scandalous music hall entertainment and subsequent, more respectable variety entertainment differ. Music hall involved a mixture of popular songs, comedy, speciality acts, and variety entertainment. The term is derived from a type of theatre or venue in which such entertainment took place. In North America vaudeville was in some ways analogous to British music hall, featuring rousing songs and comic acts.
