In local government, a city hall, town hall, civic centre (in the UK or Australia), guildhall, or (more rarely) a municipal building, is the chief administrative building of a city, town, or other municipality. It usually houses the city or town council, its associated departments, and their employees. It also usually functions as the base of the mayor of a city, town, borough, county or shire. Other terms in non-English languages are Mairie or Hôtel de ville (France), Gemeindehaus or Rathaus (Germany), Rådhus (Denmark), and Stadshus (Sweden).

By convention, until the middle of the 19th century, a single large open chamber (or "hall") formed an integral part of the building housing the council. The hall may be used for council meetings and other significant events. This large chamber, the "town hall" (and its later variant "city hall") has become synonymous with the whole building, and with the administrative body housed in it. The terms "council chambers", "municipal building" or variants may be used locally in preference to "town hall" if no such large hall is present within the building.

n many cases, "town halls" serve not only as buildings for government functions, but also have facilities for various civic and cultural activities. These may include art shows, stage performances, exhibits and festivals.

As symbols of local government, city and town halls have distinctive architecture, and the buildings may have great historical significance.
