Watermill Theatre

The Watermill Theatre is a repertory theatre in Bagnor, Berkshire. It opened in 1967 in Bagnor Mill, a converted watermill on the River Lambourn. As a producing house, the theatre has staged works that have subsequently moved on to the West End, including the 2004 revival of Sweeney Todd: The Demon Barber of Fleet Street.

The theatre has previously accepted funding from the Sackler family and has declined to comment on whether it still does.
