The London Palladium (/pəˈleɪdiəm/ pə-LAY-dee-əm) is a Grade II* West End theatre located on Argyll Street, London, in Soho. The theatre was designed by Frank Matcham and opened in 1910. The auditorium holds 2,286 people. Hundreds of stars have played there, many with televised performances. Between 1955 and 1969 Sunday Night at the London Palladium was staged at the venue, produced for the ITV network. The show included a performance by the Beatles on 13 October 1963; one newspaper's headlines in the following days coined the term "Beatlemania" to describe the hysterical interest in the band.
While the theatre hosts resident shows, it is also able to host one-off performances, such as concerts, TV specials and Christmas pantomimes. It has hosted the Royal Variety Performance 43 times, most recently in 2019.
