The '''Magellanic moorland''' or '''Magellanic tundra''' ({{lang-es|Tundra Magallánica}}) is an [[ecoregion]] on the [[Patagonia]]n archipelagos south of latitude 48° S. It is characterized by high rainfall with a vegetation of [[Shrubland|scrubs]], bogs and patches of forest in more protected areas. [[Cushion plant]]s, grass-like plants and [[bryophyte]]s are common.<ref>{{WWF ecoregion|name=Magellanic subpolar forests|id=nt0402}}</ref>
 
At present there are outliers of Magellanic moorland as far north as in the highlands of [[Cordillera del Piuchén]] (latitude 42° 22' S) in [[Chiloé Island]].<ref name=Caro88>{{cite journal |last1=Villagrán |first1=Carolina |author-link=Carolina Villagrán |date=1988 |title=Expansion of Magellanic Moorland during the Late Pleistocene: Palynological Evidence from Northern isla de Chiloé, Chile|url= |journal=[[Quaternary Research]] |volume=30 |issue= 3|pages=304–314 |doi= 10.1016/0033-5894(88)90006-3|access-date= }}</ref><ref>{{cite journal |last1=Ramírez |first1=Carlos |last2=San Martin |first2=Cristina|last3=Vidal |first3=Osvaldo|last4=Pérez |first4=Yéssica|last5=Valenzuela |first5=Jorge |last6=Solís |first6=José-Luís|last7=Toledo |first7=Gisela |date=2014 |title=Tundra Subantártica en la Isla Grande de Chiloé, Chile: Flora y vegetación turbosa de campañas|trans-title=Subantarctic Tundra in Chiloé Island, Chile: Flora and vegetation of "Campañas" peat bogs |journal=[[Anales del Instituto de la Patagonia]] |volume=42 |issue=2 |pages= 17–37|doi=10.4067/S0718-686X2014000200002 |language=Spanish |doi-access=free }}</ref> During the [[Llanquihue glaciation]] Magellanic moorland extended to the non-glaciated lowlands of Chiloé Island<ref name=Caro88/> and further north to the lowlands of [[Zona Sur|Chilean lake district]] (latitude 41° S).<ref name=Morenoetal2015>{{cite journal |last=Moreno |first=Patricio I. |last2=Denton |first2=Geoge H.|last3=Moreno |first3=Hugo |last4=Lowell|first4=Thomas V.|last5=Putnam |first5=Aaron E. |last6=Kaplan |first6=Michael R. |date=2015 |title=Radiocarbon chronology of the last glacial maximum and its termination in northwestern Patagonia|author-link2=George H.

The classification of Magellanic moorland has proven problematic as substrate, low temperatures and exposure to the ocean influences the development of the Magallanic moorland. It thus may qualify either as [[tundra|polar tundra]] or [[heathland]].<ref name=longton>{{cite book |last=Longton |first=R.E. |date=1988 |title=Biology of Polar Bryophytes and Lichen |url= |location= |publisher=Cambridge University Press |page=20 |isbn=0-521-25015-3 |author-link=|series=Studies in Polar Research }}</ref>
