Patagonia is a geographical region in southern South America that spans parts of Argentina and Chile. It includes the southern portion of the Andes mountain range, featuring lakes, fjords, temperate rainforests, and glaciers in the west, and deserts, tablelands, and steppes toward the east. The region is bounded by the Pacific Ocean to the west, the Atlantic Ocean to the east, and several waterways that connect them, including the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south.
