What is the name of the Louvre's gallery that features the French Crown Jewels?

The Louvre gallery featuring the French Crown Jewels is the Galerie d’Apollon.

Located in the Louvre Palace’s Petite Galerie, the Galerie d’Apollon is both an exhibition space and a major work of decorative art. Its current design began after a fire destroyed the earlier gallery on 6 February 1661. Louis Le Vau rebuilt the room, while Charles Le Brun developed an elaborate decorative program centred on Apollo, the sun, time, and the glory of Louis XIV.

The project was left unfinished when the royal court moved to Versailles. It was completed in the nineteenth century under architect Félix Duban, with major contributions including Eugène Delacroix’s Apollo Slaying the Python. The gallery reopened in 1851 and became one of the Louvre’s most theatrical interiors.

The French Crown Jewels have been displayed there since 1887, after the Third French Republic sold most of the collection while retaining historically important pieces. Visitors can see celebrated objects such as the Regent Diamond, the Sancy, and crowns associated with French monarchs and emperors. It is not the same as Versailles’ Galerie des Glaces.
