Jacques Mauduit (16 September 1557 – 21 August 1627) was a French composer of the late Renaissance. He was one of the most innovative French composers of the late 16th century, combining voices and instruments in new ways, and importing some of the grand polychoral style of the Venetian School from Italy; he also composed a famous Requiem for the funeral of Pierre de Ronsard.
Much of the biographical information about Mauduit comes from the writings of Marin Mersenne. Mauduit was born in Paris, and being an aristocrat, received an excellent education in humanities, languages and philosophy, but was evidently self-taught in music. Mauduit was a member of the Académie de Poésie et de Musique, the secretive group founded by Jean Antoine de Baïf to promote musique mesurée à l'antique, an attempt to recreate the rhetorical and ethical effect of ancient Greek music using modern French poetry and music. After the death of Joachim Thibault de Courville in 1581, Mauduit became the principal musician of the Académie.
