Nicolas-Guy Brenet (1 July 1728 — 21 February 1792) was a French history painter.
He studied in the atelier of François Boucher, but abandoned his master's rococo manner in the 1760s, to paint in a conscious revival of the academic classicism of Nicolas Poussin.
His enormous Battle of the Greeks and Trojans over the Body of Patroclus is an example of the new direction of official art in France.
In his unusual and precocious choice of medieval subjects, as they were commissioned by the official Bâtiments du roi, his work foreshadowed the style troubadour of the 19th century.
