Town hall of Thiais, Town hall in Val-de-Marne, France.

The town hall of Thiais occupies a municipal building at 1 rue Maurepas, in the Val-de-Marne department. Its facade follows the restrained pattern of early twentieth-century French civic architecture: a symmetrical front, regularly spaced windows and a central entrance reached from the street. The building houses the commune's administrative services and the mayor's offices.

Thiais was long governed from a combined town hall and school before the current mairie was built. The present building dates from the early twentieth century, when the commune south of Paris was still largely agricultural. It has since remained the seat of the municipal council and the mayor's offices, and later extensions added service space behind the original facade.

The salle des mariages hosts civil weddings, and the hall serves as the polling station for Thiais elections, with voters called to the bureaux de vote in the municipal building. The name Thiais comes from the Latin Thiaceus, recorded in medieval charters. Ceremonies follow the French civil code, with the mayor or a deputy officiating in the tricolour-draped room.

The town hall sits at 1 rue Maurepas in central Thiais, a short walk from the RER C station Thiais-Orly. The main entrance has level access with no steps and a doorway at least eighty centimetres wide, so wheelchair users can enter directly. Counters for civil-status documents are on the ground floor; the marriage hall is upstairs.

The town hall's address, 1 rue Maurepas, places it in the historic centre of Thiais, a commune of the Val-de-Marne about ten kilometres south-east of central Paris. The building stands near the church square, where municipal ceremonies and weekly markets have long been held.
