La Gomera is one of Spain's Canary Islands, located in the Atlantic Ocean off the coast of Africa. With an area of 370.03 square kilometres (142.87 sq mi), it is the third smallest of the eight main islands of this archipelago. It belongs to the province of Santa Cruz de Tenerife. La Gomera is the third least populous of the eight main Canary Islands with 21,503 inhabitants. Its capital is San Sebastián de La Gomera, where the cabildo insular (island council) is located.

The island is of volcanic origin and roughly circular; it is about 22 kilometres (14 miles) in diameter. The island is very mountainous and steeply sloping and rises to 1,487 metres (4,879 ft) at the island's highest peak, Alto de Garajonay. Its shape is rather like an orange that has been cut in half and then split into segments, which has left deep ravines or barrancos between them.

The local wine is distinctive and often accompanied with a tapa (snack) of local cheese, roasted pork, or goat meat. Other culinary specialities include almogrote, a cheese spread, miel de palma, a syrup extracted from palm trees, and "escaldón", a porridge made with gofio flour.

The inhabitants of La Gomera have an ancient way of communicating across deep ravines by means of a whistled speech called Silbo Gomero, which can be heard 2 miles away. This whistled language is indigenous to the island, and its existence has been documented since Roman times. Invented by the original inhabitants of the island, the Guanches, Silbo Gomero was adopted by the Spanish settlers in the 16th century and survived after the Guanches were entirely assimilated. When this means of communication was threatened with extinction at the dawn of the 21st century, the local government required all children to learn it in school. Marcial Morera, a linguist at the University of La Laguna has said that the study of silbo may help understand how languages are formed.

In the mountains of La Gomera, its original inhabitants worshipped their god, whom they called Orahan; the summit and centre of the island served as their grand sanctuary. Indeed, many of the natives took refuge in this sacred territory in 1489, as they faced imminent defeat at the hands of the Spaniards, and it was here that the conquest of La Gomera was drawn to a close. Modern-day archaeologists have found several ceremonial stone constructions here that appear to represent sacrificial altar stones, slate hollows, or cavities. It was here that the Guanches built pyres upon which to make offerings of goats and sheep to their god. This same god, Orahan, was known on La Palma as Abora and on Tenerife and Gran Canaria as Arocan. The Guanches also interred their dead in caves. Today, saints, who are worshipped through village festivals, are principally connected with Christianity. But in some aspects, the Guanches' god-like idealising of Gomeran uniqueness plays a role as well besides their pre-Christian and pre-colonial implication and shows strong local differences.

Christopher Columbus made La Gomera his last port of call before crossing the Atlantic in 1492 with his three ships. He stopped here to replenish his crew's food and water supplies, intending to stay only four days. Beatriz de Bobadilla y Ossorio, the Countess of La Gomera and widow of Hernán Peraza the Younger, offered him vital support in preparations of the fleet, and he ended up staying one month. When he finally set sail on 6 September 1492, she gave him cuttings of sugarcane, which became the first to reach the New World. After his first voyage of Discovery, Columbus again provisioned his ships at the port of San Sebastián de La Gomera in 1493 on his second voyage to the New World, commanding a fleet of 17 vessels. He visited La Gomera for the last time in 1498 on his third voyage to the Americas. The house in San Sebastián in which he is reputed to have stayed is now a tourist attraction.
