A quartiere (Italian: [kwarˈtjɛːre]; pl.: quartieri) is a territorial subdivision of certain Italian towns. The word derives from quarto (lit. 'fourth') and was thus properly used only for towns divided into four neighborhoods by the two main roads. It has been later used as a synonymous of neighbourhood, and an Italian town can be now subdivided into a larger number of quartieri. The Swiss town of Lugano (in the Italian-speaking canton of Ticino) is also subdivided into quarters.^[1]

The English word quarter to mean an urban neighbourhood (e.g. the French Quarter in New Orleans, Louisiana) is derived from the cognate old French word quartier.

Other Italian towns with other than four official neighbourhoods are frequently divided into analogous terzieri (3) or sestieri (6); some towns merely refer to these neighborhoods by the non-number-specific rioni. Quartieri, terzieri, sestieri, rioni, and their analogues are usually no longer administrative divisions of these towns, but historical and traditional communities. Sometimes towns maintain traditional cultural events linked to quartieri: a notable case is the Palio di Siena. Only in a few Italian cities, like in Florence and Bologna, a quartiere is also an administrative subdivision.
