The Queen's Theatre is a 500-seat producing theatre located in Hornchurch in the London Borough of Havering, east London. The theatre opened in its current purpose-built site on Billet Lane, Hornchurch in 1975. From 1953 to 1975 the theatre had occupied a converted, and for some time derelict, cinema on Station Lane (the site of the present Ripon House development) that had been used for storage during the Second World War. The theatre originally opened in the coronation year of Queen Elizabeth II and its name reflects this. The opening production was See How They Run.
