The London Theatre Studio was a drama and design school in Upper Street, Islington, London, from 1936 to 1939. It was directed by the French actor and director Michel Saint-Denis.

Upper Street is the main street of the Islington district of inner north London, and carries the A1 road. It begins at the junction of the A1 and Liverpool Road, continuing on from Islington High Street which runs from the crossroads at Pentonville Road/City Road and runs roughly northwards from outside the main entrance to Angel Underground station, then past the Business Design Centre, then splits at Islington Green, then past The Screen On The Green cinema, past Islington Town Hall, ending at Highbury & Islington tube station on Highbury corner, where the A1 carries on as Holloway Road.
