A commune (Spanish: comuna, IPA: [koˈmuna]) is the smallest administrative subdivision in Chile. It may contain cities, towns, villages, hamlets as well as rural areas. In highly populated areas, such as Santiago, Valparaíso and Concepción, a conurbation may be broken into several communes. In sparsely populated areas, conversely, a commune may cover a substantial rural area together with several settled areas which could range from hamlets to towns or cities.
The term "commune" is ambiguous in English, but the word is commonly used in translation for "comuna." A comuna is similar to a "county" in Anglo-American usage and practice.
Each commune is governed by a directly elected body known as a municipal council (concejo municipal) consisting of a mayor (alcalde) and a group of councillors (concejales), for a period of four years. The communal civil service administration is known as the municipality (municipalidad) and is headquartered at the mayor's office (alcaldía). According to Chilean law, a single municipality may administer one or more communes, though currently, the only such case is the municipality of Cabo de Hornos, which administers the communes of Antártica and Cabo de Hornos.
Chile's 346 communes are grouped into 54 provinces (provincia, pl. provincias), which are themselves grouped into 15 regions (región, pl. regiones).
