The Death of Marat is a 1793 painting by Jacques-Louis David depicting the artist's friend and murdered French revolutionary leader, Jean-Paul Marat. One of the most famous images from the era of the French Revolution, it was painted when David was the leading French Neoclassical painter, a Montagnard, and a member of the revolutionary Committee of General Security. Created in the months after Marat's death, the painting shows Marat lying dead in his bath after his assassination by Charlotte Corday on 13 July 1793. Art historian T. J. Clark called David's painting the first modernist work for "the way it took the stuff of politics as its material, and did not transmute it".

Jean-Paul Marat was a French political theorist, physician, and scientist. A journalist and politician during the French Revolution, he was a vigorous defender of the sans-culottes, a radical voice, and published his views in pamphlets, placards and newspapers. His periodical L'Ami du peuple made him an unofficial link with the radical Jacobin group that came to power after June 1793.
