Robinson Crusoe Island, formerly known as Más a Tierra, is the second largest of the Juan Fernández Islands, situated 670 km west of San Antonio, Chile, in the South Pacific Ocean. It is the more populous of the inhabited islands in the archipelago, with most of that in the town of San Juan Bautista at Cumberland Bay on the island's north coast.

Cuminia is a genus of flowering plant in the family Lamiaceae, first described in 1835. It contains only one known species, Cuminia eriantha. It is endemic to Robinson Crusoe Island, one of the Juan Fernández Islands in the southeast Pacific, off the coast of Chile and politically a part of that country.

Dendroseris litoralis, the cabbage tree, is a small evergreen tree species belonging to the daisy and sunflower family Asteraceae, with younger trunks ringed with pale leaf scars and distinctive rubbery, leathery leaves up to 46 centimetres (18 in) long. It is found only on the Juan Fernández Islands, west of Chile, and threatened by habitat loss. It is native only to tiny, volcanic Robinson Crusoe Island, one of the Juan Fernández Islands in the southeast Pacific, far off the coast of Chile, and home of the famed Juania australis and many other fascinating endemic plants. This strange, small tree has literally been brought back from the brink of extinction. It had been reduced to only a few individuals by feral goats on the island, and is still considered critically endangered. It grows into a small, gnarled tree with several somewhat palm-like crowns of very large, ovate leaves on whitish, green-spotted leaf stalks and pendent inflorescences of bright orange, tassel-like 'flowers' (capitula). It is easy to cultivate and enjoys a cool, humid climate. It is hardy to light freezes and coastal conditions.

The Juan Fernández firecrown is a hummingbird found today solely on Isla Róbinson Crusoe, one of the three-island Juan Fernández archipelago belonging to Chile. It is non-migratory and shares the island with its smaller relative the green-backed firecrown.

Lactoris fernandeziana is a flowering shrub endemic to the cloud forest of Masatierra — Robinson Crusoe Island, of the Juan Fernández Islands archipelago of Chile.

The Juan Fernández petrel is a species of seabird in the family Procellariidae. It nests on a single island off the coast of Chile, in the Juan Fernández Archipelago. It was previously classified as a subspecies of the white-necked petrel, which is found in tropical waters of the Pacific and Indian Oceans.

Podophorus is an extinct genus of plants in the grass family. The only known species is Podophorus bromoides, which was native to Robinson Crusoe Island in the South Pacific Ocean. This is one of the Juan Fernández Islands, part of the Republic of Chile. The plant was last collected in the wild in the mid-19th century and is now considered extinct. A genetic analysis of the type material found it to be most closely related to Megalachne, also endemic to the Juan Fernández archipelago. This clade was in turn found to be nested within a paraphyletic Festuca, most closely related to F. pampeana of South America.

San Juan Bautista is the main town in the Juan Fernández Islands of Chile. Some sources say it was founded in 1877, while others give an earlier date of 1750. It is located on Cumberland Bay on the center of the northeast coast of Robinson Crusoe Island.
