The Melun Diptych is a two-panel oil painting by the French court painter Jean Fouquet (c. 1420–1481) created around 1452. The name of this diptych came from its original home in the Collegiate Church of Notre-Dame in Melun. The left panel depicts Étienne Chevalier with his patron saint St. Stephen and the right panel depicts the Virgin and Christ Child surrounded by cherubim. Each wooden panel measures about 93 by 85 centimeters and the two would have been hinged together at the center.
The two pieces, originally a diptych, are now separated. The left panel is in the Staatliche Museen in Berlin and the right panel is at the Royal Museum of Fine Arts, Antwerp, Belgium. A self-portrait medallion is also associated with the two panels. Measuring 6 centimeters in diameter, it would have adorned the frame, and consists of copper, enamel, and gold. The medallion is now in the Louvre in Paris, France.
