Leochares (Greek: Λεοχάρης) was a Greek sculptor from Athens, who lived in the 4th century BC.
Leochares worked at the construction of the Mausoleum of Maussollos at Halicarnassus, one of the "Seven Wonders of the Ancient World". The Diana of Versailles is a Roman copy of his original (circa 325 BC). He is also thought to be the creator of the celebrated Apollo Belvedere, of which a Roman copy is currently housed in Vatican City.
Of his portrait-statues, the most celebrated were those of Philip, Alexander, Amyntas III, Olympias, and Eurydice II, which were made of ivory and gold, and were placed in the Philippeion a circular building in the Altis at Olympia, erected by Philip II of Macedon in celebration of his victory at Battle of Chaeronea (338 BC)
（Λεωχάρης). A Greek sculptor, of Athens, who (about B.C. 350) was engaged with Scopas in the adornment of the Mausoleum (q.v.) of Halicarnassus. One of his most famous works was the bronze group of Ganymede and the Eagle, a work remarkable for its ingenious composition, which boldly ventures to the verge of what is allowed by the laws of sculpture, and also for its charming treatment of the youthful form as it soars into the air. It is apparently imitated in a well-known marble group in the Vatican, half life-size. See Perry, Greek and Roman Sculpture, ch. xxxix. (London, 1882).
