A 'quartiere' (plural: 'quartieri') is a subdivision of certain
Italian towns. The word is from ''quarto'', or fourth, and was thus properly used only for towns divided into four neighborhoods; from it is derived the English word "quarter" to mean a neighborhood (e.g. the
French Quarter in
New Orleans,
Louisiana).
Other Italian towns with other than four official neighborhoods 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, most often seen in their sharpest relief in the town's annual
palio.
