Louis-Claude Daquin (or d'Acquin), (July 4, 1694 – June 15, 1772) was a French composer of Jewish birth writing in the Baroque and Galant styles. He was a virtuoso organist and harpsichordist.

At the age of eight, he conducted his own choral work Beatus Vir.
Daquin's surviving music includes four harpsichord suites, a Nouveau livre de noëls for organ and harpsichord (settings of Christmas pastorals, which include some of his harpsichord improvisations), a cantata, and an air à boire. Among the most famous of his works are the Swiss Noel (Noël Suisse, No. XII of his Nouveau livre), and Le coucou ("The Cuckoo") which is from his 1735 harpsichord suite.
Among technical innovations, his Trois cadences for harpsichord contains a triple trill.
