Alexander Selkirk in the context of "Robinson Crusoe"

The Juan Fernández Islands (Spanish: Archipiélago Juan Fernández) are a sparsely inhabited series of islands in the South Pacific Ocean, reliant on tourism and fishing. Situated 670 km (362 nmi; 416 mi) off the coast of Chile, they are composed of three main volcanic islands: Robinson Crusoe, Alejandro Selkirk, and Santa Clara. The group is part of Insular Chile.

The islands are primarily known for having been the home to the marooned sailor Alexander Selkirk for more than four years from 1704, which may have inspired English writer Daniel Defoe's Robinson Crusoe. Most of the archipelago's present-day inhabitants reside on Robinson Crusoe Island, and mainly in the capital, San Juan Bautista, located at Cumberland Bay on the island's north coast.

Robinson Crusoe Island (Spanish: Isla Róbinson Crusoe, pronounced [ˈisla ˈroβinsoŋ kɾuˈso]) is the largest of the Juan Fernández Islands, situated 670 km (362 nmi; 416 mi) west of San Antonio, Chile, in the South Pacific Ocean. It is the more populous of the inhabited islands in the archipelago (the other being Alejandro Selkirk Island), with most of that in the town of San Juan Bautista at Cumberland Bay on the island's north coast. The island was formerly known as Más a Tierra ('Closer to Land').

From 1704 to 1709, the island was home to the marooned Scottish sailor Alexander Selkirk, who at least partially inspired novelist Daniel Defoe's fictional Robinson Crusoe in his 1719 novel, although the novel is explicitly set in the Caribbean. This was just one of several survival stories from the period of which Defoe would have been aware. To reflect the literary lore associated with the island and attract tourists, the Chilean government renamed it Robinson Crusoe Island in 1966.

Alejandro Selkirk Island (Spanish: Isla Alejandro Selkirk), previously known as Más Afuera (Farther Out (to Sea)) and renamed after the marooned sailor Alexander Selkirk, is the largest and most westerly island in the Juan Fernández Archipelago of the Valparaíso Region of Chile. It is situated 180 km (100 nmi; 110 mi) west of Robinson Crusoe Island in the southeastern Pacific Ocean.

The Archipelago was home to the marooned sailor Alexander Selkirk from 1704 to 1709, and is thought to have inspired English novelist Daniel Defoe's fictional Robinson Crusoe in his 1719 novel about the character (although the novel is explicitly set in the Caribbean, not in the Juan Fernández Islands). This was just one of several survival stories from the period that Defoe would have been aware of. To reflect the literary lore associated with the island and attract tourists, the Chilean government renamed the place Alejandro Selkirk Island in 1966.
