The St. Olaf Choir is an American collegiate choir based at St. Olaf College in Northfield, Minnesota, founded in 1912 and specialising in choral, sacred and classical repertoire. Rooted in the Scandinavian-Lutheran choral tradition, the ensemble emphasises a cappella singing of liturgical and concert works and has maintained a programme of touring, recordings and commissioning of contemporary choral compositions that contributed to the development of collegiate choral practice in the United States.
