Joseph Boze (* 7. February 1745 in Martigues; 25. January 1826 in Paris) was a French portrait painter.
Already at a young age he was occupied with art and design. At the age of 17 he visited the renowned École académique de dessin in Marseille, today's École Supérieure des Beaux-Arts de Marseille. Later he went to Paris and became a pupil of the French court painter Maurice Quentin de La Tour (1704-1788). Boze became famous for his portraits of French nobles from the time of the Ancien Régimes.
During the French Revolution he painted personalities of the new state leadership such as Mirabeau, Maximilien de Robespierre and Jean Paul Marat. After testifying in favour of Marie Antoinette in the trial, Boze was arrested in the conciergerie. After the fall of Robespierre he was released and emigrated to England. In 1798 he returned to Paris, where he worked as a painter until his death in 1826.
