Nothofagus betuloides, Magellan's beech[1] or guindo, is a tree native to southern Patagonia.

In 1769, Sir Joseph Banks collected a specimen of the tree in Tierra del Fuego during Captain Cook's first voyage.

One specimen growing near the southeastern corner of Hornos Island (Cape Horn) was identified in 2019 as the southernmost tree in the world.

In the exposed sites of its southerly coastal or Andean distribution, the species grows as a wind formed shrub.

Trees planted in the Faroe Islands, which were imported directly from its southernmost distribution in Tierra del Fuego, have turned out to be very hardy.
