Sancta Civitas (The Holy City) is an oratorio by Ralph Vaughan Williams.

Vaughan Williams began working on the piece from a rented furnished house in the village of Danbury, Essex, found for him by his former pupil, Cecil Armstrong Gibbs.

Late in life, Vaughan Williams called Sancta the favourite of his choral works.

[3] Sancta Civitas is scored for a full orchestra, with optional organ, as well as a mixed chorus, a semi-chorus, a "distant chorus" of boys (accompanied by an offstage trumpet), a baritone solo, and a tenor solo.

Although Sancta Civitas is presented in the score as a single continuous piece, recordings typically divide it into 10 sections as follows: The piano reduction of the orchestral parts used in the first vocal score was prepared by fellow composer Havergal Brian.
