Bridewell Theatre is a theatre in Blackfriars, London, operated as part of the St Bride Foundation Institute, named after nearby St Bride's Church on Fleet Street. Established in 1994 by Carol Metcalfe after being converted from a disused swimming pool, it became a venue and company hosting fringe theatre productions in central London. Formerly occupied by the Bridewell Theatre's own theatre company, it became involved in the development and introduction of Stephen Sondheim's works in the UK, facilitating the world premiere of his production Saturday Night in 1997.
