Aysén Region
administrative division of Chile
The Aysén del General Carlos Ibáñez del Campo Region (Spanish: Región de Aysén, pronounced [ajˈsen], or Región de Aysén del General Carlos Ibáñez del Campo), often shortened to Aysén Region or Aisén, is one of Chile's 16 regions. It is the third-largest region in area and the least populous, with a population of 102,317 as of 2017. The capital of the region is Coyhaique, the region's former namesake. The region's current namesake is the former President of Chile, General Carlos Ibáñez del Campo.
The landscape is marked by several glaciations that formed many lakes, channels and fjords. The region contains icefields including the Northern Patagonian Ice Field and the Southern Patagonian Ice Field, the world's third largest after those in Antarctica and Greenland. The northern half of the region feature a north-south string of volcanoes. While the western part of the region is densely vegetated and mountainous, the eastern reaches contain open grasslands and much flat and rolling terrain.
Aysén Region was the last major area to be effectively incorporated into the Republic of Chile, with the first permanent settlements emerging in the second half of the 19th century and the inland part being settled at the turn of the century. Until the construction of Route 7 (the Carretera Austral, or Southern Highway) in the 1980s, the only overland routes from north to south through the region were extremely primitive tracks.
This brief starts where responsible research should: with the source description of “Aysén Region” as administrative division of Chile. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as administrative division of Chile. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q2181. Authority coordinates are -45.570, -72.066. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2017.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
