Saint Helena (, US: ; US: ) is a volcanic tropical island located in the South Atlantic Ocean, west of Africa. The nearest countries geographically are Angola and Namibia. The island is about 1,950 km (1,210 mi) west of Angola, and 4,000 km (2,500 mi) east of Rio de Janeiro, Brazil. It is one of the three constituent parts of Saint Helena, Ascension and Tristan da Cunha, a British overseas territory.

Saint Helena measures about 16 by 8 km (10 by 5 mi) with a population of 4,439 in the 2021 census. It was named after Saint Helena (c. AD 246/248–330), the mother of the Roman emperor Constantine I. It is one of the most remote major islands in the world and was uninhabited until the 16th century, when discovered by the Portuguese explorers en route around the continent of Africa in 1502. For about the next four centuries, the island was an important stopover for ships between Europe and Asia sailing around the African continent, before the opening of the shortcut Suez Canal in 1869.

The primary method of reaching Saint Helena is by its airport. It is also served by cargo ships.

According to long-established tradition, the island was sighted on 21 May 1502 by the four ships of the 3rd Portuguese Armada, commanded by João da Nova, a Galician navigator in the service of Portugal, during his return voyage to Lisbon, who named it Santa Helena after Saint Helena of Constantinople. This tradition was reviewed by a 2022 paper which concluded that the Portuguese chronicles published at least fifty years after the sighting are the sole primary source for the discovery. Although contradictory in describing other events, these chronicles almost unanimously claim that João da Nova found Saint Helena sometime in 1502, although none of them gives a precise date.

However, there are several reasons to doubt that da Nova made this discovery:
