Annick Massis (born Jacqueline Dubreuil; 31 January 1958) is a French operatic soprano whose career is primarily based in Europe. She performed roles from various classical music eras, spanning from baroque, operas by Mozart, to 19th-century Italian and French repertoire.

Jacqueline Dubreuil was born in the 15th arrondissement of Paris, to singer parents: mother specialising in operetta, father being a baritone in the Choir of Radio France. After obtaining double degree in history and English, she worked as a school teacher till 28, during which she took masterclasses and met her teacher Isabel Garcisanz. Two years later, Gabriel Dussurget, founder of the Aix-en-Provence Festival, introduced her to conductor Bernard Thomas, who engaged her in Great Mass in C minor and the entire oratorio repertoire after a simple audition.
