Areas of Argentina

Provinces

The Provinces of Argentina are often grouped into six geographical regions. From North to South and West to East, these are:

Argentina North West: Jujuy, Salta, Tucumán, Catamarca, La Rioja 

Gran Chaco: Formosa, Chaco, Santiago del Estero

Mesopotamia (or Littoral): Misiones, Entre Ríos, Corrientes 

Cuyo: San Juan, Mendoza, San Luis

Pampas: Córdoba, Santa Fe, La Pampa, Buenos Aires 

Patagonia: Rio Negro, Neuquén, Chubut, Santa Cruz, Tierra del Fuego

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 Sierra 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, South Western 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.
