Jean-Nicolas Geoffroy (1633 – March 11, 1694) was a French harpsichordist and organist. His birthplace is unknown; he died in Perpignan.

His life before 1690 is unknown; he was probably a pupil of Nicolas Lebègue and served as titular organist of the Saint-Nicolas-du-Chardonnet church in Paris. He was considered an expert in organ building and at some point in life settled in Perpignan where he played the organ of Perpignan Cathedral (Cathédrale Saint-Jean-Baptiste).

Geoffroy's harpsichord oeuvre is, along with those of François Couperin and Jean-François Dandrieu, one of the most important contributions to French music of the Baroque era. A single collection of his pieces survives in manuscript. It contains 255 pieces and is unique for European music of the late 17th century because the pieces systematically explore all major and minor keys. Read more on Last.fm.
