What is the name of the strait at the southern tip of South America?

The strait at the southern tip of South America is the Strait of Magellan. It is a navigable sea route in southern Chile that separates mainland South America from the Tierra del Fuego archipelago.

Ferdinand Magellan’s expedition became the first European expedition to navigate the passage in 1520. Magellan originally called it the Strait of All Saints because the ships entered it on 1 November, but the Spanish crown later renamed it in his honor. The passage connects the Atlantic and Pacific oceans through a sheltered but complex network of channels.

The Strait of Magellan was historically important because it offered a safer alternative to the stormy Drake Passage around Cape Horn. It was a major route for ships until the Panama Canal opened in 1914. The Beagle Channel is another passage in the region, but it lies south of the Strait of Magellan within Tierra del Fuego.
