Élisabeth Jacquet de La Guerre (1665–1729) was a prominent French composer and harpsichordist. Born into a family of musicians, she gained early recognition for her prodigious talent, performing at Louis XIV's court by age five. She became a court musician and composed extensively for Louis XIV. Her notable works include the Premier livre de pièces de clavessin, one of the few collections of harpsichord pieces from 17th-century France. She composed a ballet, Les Jeux à l'honneur de la victoire, and her opera Céphale et Procris marked the first opera by a woman in France.
