Charles Hardouin (1694 in Brittany, fl.
Paris – 1718) was a French operatic baritone (basse taille).
Beginning his career as a cathedral singer, Hardouin was engaged by the Paris Opéra as a principal singer around 1693–1694, though from 1697 onwards he was eclipsed by the more powerful Gabriel-Vincent Thévenard.
He was still singing in 1718 when he was acclaimed as Poliphème in Lully's Acis et Galatée.
