St Luke's is a historic Anglican church building in the London Borough of Islington. It is now a music centre operated by the London Symphony Orchestra and known as LSO St Luke's. It is the home of the LSO's community and music education programme, LSO Discovery. The main body of the church seats up to 372 and is used by the LSO for rehearsals, and by a wide variety of musicians for performances and recording. Additional rooms in the crypt provide practice facilities for professional musicians, students and community groups.
