The Great Cameo of France () is a five-layered sardonyx Imperial Roman cameo of either about 23 AD, or 50–54 AD. It is 31 cm by 26.5 cm. It is now in the Bibliothèque Nationale in Paris.

It is the largest Roman imperial cameo to have survived.  It would have been an object of great value and prestige, almost certainly made for a member of the ruling Julio-Claudian dynasty.  It is carved with twenty-four figures, divided into three levels.  The identity of some figures, and the meaning and iconographic intent of the work have been much debated, but it is clear that the piece is intended to assert the continuity and dynastic legitimacy of the Julio-Claudian dynasty.

Iconography
The interpretation of the family group alters with the date given to the gem. In the upper level are its deceased or deified members including Divus Augustus. The surrounding figures may be Drusus the Younger (son of Tiberius), and Drusus the Elder (brother of Tiberius) flying on Pegasus.

In the middle level appear the emperor Tiberius flanked by his mother Livia; standing in front of them are Germanicus, Tiberius's designated heir, together with his wife Agrippina the Elder, behind them the future emperor Nero and the figure of Providentia (Foresight); behind Livia and Tiberius are Claudius, emperor if the cameo was made in –54 AD, and his wife Agrippina the Younger. Agrippina the Younger's hairstyle seems to confirm a date for the cameo between her marriage to Claudius in 49 and the accession of her son Nero as the fifth emperor of Rome in 54.

Alternatively, the cameo was commissioned  to celebrate Tiberius adoption of his grandchildren, the sons of Germanicus, as heirs in 23 AD, and the dynastic stability it ensured, comparable to the earlier adoption of Germanicus by Tiberius in 4 AD, also referenced on the cameo and in the Gemma Augustea.  In the lowest level are captive barbarians.

History
It appears to have come to France from the treasury of the Byzantine Empire, and is first attested in the first inventory of the treasure of the Sainte Chapelle before 1279.  It was then known as the Triumph of Joseph at the Court of the Pharaoh. It was sold by Baldwin II, emperor of the Latin Empire, to Louis IX of France.   It is then mentioned in the 1279 inventory list of Sainte-Chapelle in Paris. Philip VI of France  consecutively sent it to Pope Clement VI in Avignon in 1342 or 1343 possibly as collateral for financial support. In 1363, Antipope Clement VII then returned it to the Dauphin,  the later Charles V of France. The cameo was then brought to Saint-Chapelle in 1379.

The antiquary Nicolas-Claude Fabri de Peiresc, who saw the gem in 1620, was the first modern to realize the gem showed a Julio-Claudian group.

Louis XVI of France then claimed the cameo in 1792 and brought it to the Cabinet des médailles in order to protect it from the French revolutionaries. It was briefly stolen in 1804 but recovered in Amsterdam in 1805 without its original gold frame, which was replaced by a bronze one that in turn was lost until 1912.
