Who runs local government in Argentina?
Argentina is a federation of 23 provinces plus the Autonomous City of Buenos Aires, and the provinces, not the national government, decide how local government works. Each province writes its own constitution and sets up its own municipal system, so there are six different kinds of local government across the country (about 2,311 local units in 2021). Indigenous communities can register as legal bodies and hold land communally, but customary leaders have no general governing role.

The levels of government below the nation
| Level | How it is chosen | What it does |
|---|---|---|
| Provinces (23) + Autonomous City of Buenos Aires | Governor and provincial legislature directly elected; Buenos Aires City elects its own head of government (jefe de gobierno) and legislature | Write their own constitutions, run police, schools, hospitals, courts and set the rules for their municipalities. |
| Local governments (about 2,311 in 2021: 1,179 municipios and 1,132 other types) | Mayor (intendente) and council (concejo deliberante) usually directly elected; rules differ by province | Local services such as street lighting, waste, local roads, markets and planning. Smaller places are run as comunas, comisiones de fomento or comisiones municipales with fewer powers. |
| Sub-municipal units (e.g. 15 comunas in Buenos Aires City; rural communes in Chubut and Tucumán) | In Buenos Aires City each comuna elects a 7-member board (junta comunal) | Neighbourhood maintenance and local participation; limited budgets. |
Three questions about local power in Argentina
Are local leaders elected?
Provincial governors and legislators, mayors and councillors are elected. Buenos Aires City comuna boards are elected. Indigenous community leaders are chosen by community custom. Co-operative boards are elected by members.
Which laws set up local government?
Municipal autonomy is in the national constitution (Art. 5 and Art. 123) but each province decides how much autonomy its municipalities actually get. Indigenous communities are recognised in the constitution and in Law 23.302. Sociedades de fomento are private associations, not government.
Who are local leaders accountable to?
Local officials answer to voters and to provincial law and courts. Provinces can intervene in municipalities under their own constitutions, and the federal government can intervene in a province under Art. 6 of the national constitution.
Traditional and customary authority
The 1994 constitution (Art. 75, para. 17) recognises the 'ethnic and cultural pre-existence' of Indigenous peoples, the legal personality of their communities and their communal ownership of the lands they traditionally occupy. Under Law 23.302, communities can register with the national Indigenous affairs institute (INAI) or a provincial registry and gain legal personality. Communities choose their own leaders (for example a lonko among the Mapuche, or a cacique) by their own customs, and these leaders speak for the community in land and consultation matters. They do not run a separate level of government, and land conflicts are decided by ordinary courts. The Catholic Church has a special constitutional status (Art. 2 says the federal government 'supports' it), but religious leaders hold no formal local power.
Community and neighbourhood power
Neighbourhood associations called sociedades de fomento (development societies) and juntas vecinales are common, especially in Buenos Aires province; many are registered civil associations that lobby the municipality, run clubs and sometimes manage small works. In some provinces juntas vecinales are themselves a type of local government. Service co-operatives (cooperativas) run electricity, water or gas in many small towns, and their boards are elected by members. Soup kitchens (comedores) and community organisations distribute food in poorer areas, often with state funding.
Points to know
- Because each province designs its own system, a town of 2,000 people can be a full municipality in one province and only a 'commune' in another.
- Art. 123 of the 1994 constitution says provinces must guarantee municipal autonomy, but the province of Buenos Aires still runs its 135 municipalities (called partidos) under one provincial organic law rather than letting them write their own charters.
- About 80% of Argentina's local governments have fewer than 10,000 people, while Buenos Aires City and Córdoba have over a million each (OECD figures).
- Buenos Aires City has had an elected head of government only since the 1994 reform; before that the President appointed the mayor.
