Johann Peter Melchior (8 March 1747 – 13 June 1825) was a German porcelain modeller.
He was interested in art from an early age and was apprenticed to a sculptor in Düsseldorf.
He made a name for himself in the porcelain trade and was named Modellmeister at the acclaimed Höchst porcelain factory in 1767, a post he held until 1779.
Melchior was a transitional figure between Rococo and Neoclassicism.
His early work was graceful and often sentimental, and his favourite subjects included religious groups, pastoral scenes, characters from mythology, and children.
