en Regions of Argentina

The provinces of Argentina are often grouped into eight geographical regions.

Regions

From West to East and North to South, these are:

Pampas region: Buenos Aires, Córdoba, Santa Fe, La Pampa and Entre Ríos
Argentine Northwest: Jujuy, Salta, Tucumán, Catamarca, Santiago del Estero and La Rioja
Cuyo region: San Juan, Mendoza and San Luis
Argentine Northeast: Misiones, Corrientes, Formosa and Chaco
Eastern Patagonia: Río Negro, Neuquén, Chubut, Santa Cruz and Tierra del Fuego
Argentine Antarctica: Tierra del Fuego

And is sometimes considered as a region:

Argentine Littoral: Entre Ríos, Misiones, Corrientes, Santa Fe, Formosa and Chaco

Nevertheless, there are different approaches to the Argentine regions. The Pampas are often separated into Humid Pampa and Dry Pampas, and sometimes in Llanura Pampeana and Sierras Pampeanas. Other geographical analysis include other defined regions, being Comahue and Chaco Central among the most common.

Regardless of the regions system used, some provinces are shared by more than one region. For instance, Southwestern Santiago del Estero is sometimes considered part of the Sierras area, or even the Humid Pampa, while the Southern part of La Pampa is sometimes called Dry Pampa and included in Patagonia. Finally, La Rioja is sometimes considered part of Cuyo region instead of the Northwest.

Finally, the portion of the Antarctica claimed by Argentina is known as Argentine Antarctica, in which lay a number of Argentine bases.
