The Barnfield Theatre is a theatre in Exeter, England, located near the centre of the city on Barnfield Road, Southernhay. It was originally built as the Barnfield Hall near the end of the 19th century by Exeter Literary Society, and was converted to a theatre in 1972.
Today the theatre is operated as a charity and is used as a venue for amateur and professional theatrical companies. The building is owned by Exeter City Council and leased to Barnfield Theatre Limited, who run the theatre. In January 2007 it received £200,000 to refurbish its interior.
