Nicolas Chaperon (Châteaudun, bapt. 19 October 1612 e Lyon 1656) was a French painter, draughtsman and engraver, a student in Paris of Simon Vouet whose style he adopted before he was further matured by his stay in Rome (1642-51) in the studio of Nicolas Poussin. In 1653-55 the consuls de Lyon called him to decorate the hôtel de ville but Chaperon dying almost as soon as he arrived, the commission passed to Thomas Blanchet. Chaperon made a name for himself with his suite of engravings after the Raphael Loggie of the Vatican, Rome, 1649, but art historians remember him for the stream of fulminating invective with which Poussin in his correspondence with Paul Freart de Chantelou described this unruly and vindictive practician who refused to carry through his copy of a Transfiguration. So little is known of Chaperon that this episode stands out.
