Nogent-sur-Seine (French pronunciation: [nɔʒɑ̃ syʁ sɛn] ⓘ) is a commune in the Aube department in north-central France.

The headquarters of The Soufflet Group is located here, as is the Musée Camille Claudel.

Sculptor Camille Claudel lived in Nogent-sur-Seine with her family from 1876 to 1879.

Frédéric Moreau, the hero of Gustave Flaubert's novel Sentimental Education, is a native of Nogent-sur-Seine.

Fragments of it were used in 1817 in making the canopy over the graves of Pierre Abélard and Héloïse d'Argenteuil at the Père Lachaise Cemetery.
