Town hall of Paris 7th arrondissement, Administrative building in 7th arrondissement, France.

The town hall of Paris 7th arrondissement, also called hôtel de Villars, occupies a 17th-century hôtel particulier at 116 rue de Grenelle. Its pale stone facade centres on a tall archway with a coffered vaulted passage, flanked by two smooth columns with carved capitals; winged figures recline on the spandrels and a carved panel reads "MAIRIE DU VIIME ARRONDT". A shield-like crest and carved frieze top the symmetrical composition.

Built between 1645 and 1657 as the hôtel particulier of Jacques le Coigneux, président à mortier, the building became the Paris home of Marshal Claude Louis Hector de Villars, who rented then bought it in 1710 and had Germain Boffrand remodel it. A western extension, the petit hôtel de Villars, was added between 1714 and 1717. The City of Paris bought it in 1862 for 1,350,000 francs, Joseph Uchard carried out works, and on 1 August 1865 the 7th arrondissement town hall moved here from 7 rue de Grenelle.

The council chamber is named Salle Frédéric-Dupont after former mayor Édouard Frédéric-Dupont. The building, called hôtel de Villars, keeps the name of Claude Louis Hector de Villars, who bought it in 1710 as his Paris home. Marriages are held in the salle des mariages, one of the rooms listed in the 2025 heritage inscription.

The town hall is at 116 rue de Grenelle, near the Assemblée nationale metro stop on line 12 and the Musée d'Orsay RER C station. The entrance arch opens onto a courtyard; the garden facade, inscribed in 1926, is best seen from the garden side. The council room is named salle Frédéric-Dupont after a former mayor.

The 1926 listing covered only the garden-facing facade; a 2025 decree replaced it, extending protection to all facades and roofs, the courtyard ground, the garden and its wall, the entrance hall, the staircase with its cage and first-floor landing, the east and west corridors, the council room (former games salon), the mayor's office, the chief-of-staff office and the wedding room.
