The Novello Theatre is a West End theatre on Aldwych, in the City of Westminster.
The theatre was built as one of a pair with the Aldwych Theatre on either side of the Waldorf Hotel, both being designed by W. G. R. Sprague. The theatre opened as the Waldorf Theatre on 22 May 1905, and was renamed the Strand Theatre, in 1909. It was again renamed as the Whitney Theatre, in 1911 before again becoming the Strand Theatre, in 1913. In 2005, the theatre was renamed by its owners (Delfont Mackintosh Theatres) the Novello Theatre in honour of Ivor Novello, who lived in a flat above the theatre from 1913 to 1951.
The black comedy Arsenic and Old Lace had a run of 1337 performances here in the 1940s, and Sailor, Beware! ran for 1231 performances from 1955. Stephen Sondheim's musical A Funny Thing Happened on the Way to the Forum opened here on the day of Kennedy's assassination, running for nearly two years. In 1971, the comedy No Sex Please, We're British opened here, remaining for over 10 years of its 16-year run until it transferred to the Garrick Theatre in 1982.
The theatre was extensively refurbished in 1930 and again in the early 1970s. It was Grade II listed by English Heritage on 20 July 1971. After The Rat Pack: Live From Las Vegas in 2005, its 100th anniversary year, the theatre was extensively refurbished. The current seating capacity is 1,105.
The theatre reopened on 8 December 2005 with the Royal Shakespeare Company's annual London season, playing to 4-week runs of Twelfth Night, The Comedy of Errors, A Midsummer Night's Dream and As You Like It, concluding in March 2006.
This theatre is one of the 40 theatres featured in the 2012 DVD documentary series Great West End Theatres, presented by Donald Sinden.
