Chapelle du Lycée Hoche de Versailles, Classical chapel and former convent in Versailles, France.

The Chapelle du Lycée Hoche de Versailles is a classical chapel and former convent with neoclassical architecture, symmetrical designs, and soaring ceilings. Its interior displays ornate details on walls and vaults that once served religious and educational purposes.

Marie Leszczyńska founded the convent in 1767, after her father Stanisław's death, on land at Clagny given by Louis XV; Richard Mique designed it. The queen died in 1768, and Louis XV inaugurated the convent on 29 September 1772 with his daughters, Madame Adélaïde having overseen the works. Suppressed at the Revolution, the buildings housed a lycée from the early 19th century, named Lycée Hoche in 1888.

The convent church, now the chapel of Lycée Hoche, keeps the name Notre-Dame-du-Mont-Carmel. Its interior holds twenty bas-reliefs of the Life of the Virgin by Joseph Deschamps, set above the windows. The dome was painted from 1777 by Biard, who died before finishing; Jean-Jacques Lagrenée completed the four pendentives with the Church Fathers Jerome, Augustine, Chrysostom and Gregory.

The chapel stands inside the Lycée Hoche, in the former convent buildings on the Clagny estate given by Louis XV. Access follows school life, so visits are arranged around term time rather than daily opening. The church occupies the centre of Richard Mique's orthogonal plan, with the convent wings around it; enter from the school side.

The church was built to a Greek-cross plan after Madame Adélaïde took over the project, replacing Marie Leszczyńska's original basilical design. Its slate roof forms a dome carried on four half-domes, a feature linked to Byzantine architecture. Twenty bas-reliefs of the Life of the Virgin by Joseph Deschamps sit above the windows.
