Political divisions

At a state level, Patagonia visually occupies an area within two countries: approximately 10% in Chile and approximately 90% in Argentina. Both countries have organized their Patagonian territories into nonequivalent administrative subdivisions: provinces and departments in Argentina, as well as regions, provinces, and communes in Chile. As Chile is a unitary state, its first-level administrative divisions—the regions—enjoy far less autonomy than analogous Argentine provinces. Argentine provinces have elected governors and legislatures, while Chilean regions had government-appointed intendants prior to the adoption of elected governors from 2021.

The Patagonian Provinces of Argentina are Neuquén, Río Negro, Chubut, Santa Cruz, and Tierra del Fuego. The southernmost part of Buenos Aires Province can also be considered part of Patagonia.

The two Chilean regions undisputedly located entirely within Patagonia are Aysén and Magallanes. Palena Province, a part of the Los Lagos Region, is also located within Patagonia. By some definitions, Chiloé Archipelago, the rest of the Los Lagos Region, and part of the Los Ríos Region are also part of Patagonia.
