Pierre Julien (20 June 1731 – 17 December 1804) was a French sculptor who worked in a full range of rococo and neoclassical styles.
He served an early apprenticeship at Le Puy-en-Velay, near his natal village of Saint-Paulien, then at the École de dessin of Lyon, then entered the Parisian atelier of Guillaume Coustou the Younger. In 1765 he won a Prix de Rome for sculpture with a bas-relief panel of a subject from Antiquity and entered the École royale des élèves protégés, which offered a special course of study under the direction of the painter Louis-Michel van Loo. He was a pensionnaire at the French Academy in Rome, 1768 to 1773, where he was influenced by the tide of neoclassicism that affected his fellow students. As pensionnaires were expected to do, he sent back to France a marble copy from the Antique, slightly reduced in scale, of the so-called Cleopatra, the Vatican's Sleeping Ariadne, which remains at Versailles.
On his return to France and his former master, he worked on the sculpture for the mausoleum of Louis, le Grand Dauphin in the cathedral of Sens. After a failed try in 1776, with his Ganymede, he was received by the Académie royale de peinture et de sculpture in 1778, with a Dying Gladiator for his morceau de réception He was named one of the original members of the Institut de France, 1795, and a chevalier of the Légion d'Honneur, 1804.
