Guillaume-Gabriel Nivers (ca. 1632 – 13 November 1714) was a French organist, composer and theorist. His first livre d'orgue is the earliest surviving collection with traditional French organ school forms. Nivers's other music is less known; however, his treatises on Gregorian chant and basso continuo are still considered important sources on 17th century liturgical music and performance practice.
