This is a list of islands in the Atlantic Ocean, the largest of which is Greenland. Note that the definition of the ocean used by the International Hydrographic Organization (IHO) excludes the seas, gulfs, bays, etc., bordering the ocean itself. Thus, for instance, not all of the islands of the United Kingdom are actually in or bordering on the Atlantic. For reference, islands in gulfs and seas are included in a separate section. Oceanic islands are formed by seamounts rising from the ocean floor with peaks above the surface of the ocean and are not parts of continental tectonic plates.

List of islands in the Atlantic Ocean in the context of Macaronesia
24°15′24″N 22°28′16″W / 24.25667°N 22.47111°W
Macaronesia (Portuguese: Macaronésia; Spanish: Macaronesia) is a collection of four volcanic archipelagos in the North Atlantic Ocean, off the coast of North Africa and Europe. Each archipelago is made up of a number of Atlantic oceanic islands, which were formed by seamounts on the ocean floor whose peaks have risen above the ocean's surface.
List of islands in the Atlantic Ocean in the context of Teide
Teide (Spanish: El Teide) or Mount Teide (Pico del Teide, pronounced [ˈpiko ðel ˈtejðe]; 'Peak of Teide') is a volcano on Tenerife in the Canary Islands. Its summit (at 3,715 m (12,188 ft)) is the highest point in the Canary Islands and the highest point above sea level in the islands of the Atlantic. If measured from the ocean floor, its height of 7,500 m (24,600 ft) makes Teide the third-highest volcano in the world; UNESCO and NASA rank it as Earth's third-tallest volcanic structure. Teide's elevation above sea level makes Tenerife the tenth highest island in the world.
Teide started forming 170,000 years ago due to volcanic activity following a catastrophic landslide. Teide's base is situated in Las Cañadas crater (the remains of an older, eroded, extinct volcano) at a height of around 2,190 m (7,190 ft) above sea level. Teide is an active volcano: its most recent eruption occurred in late 1909 from the El Chinyero vent on the northwestern Santiago rift. The United Nations Committee for Disaster Mitigation designated Teide a Decade Volcano because of its history of destructive eruptions and its proximity to several large towns, of which the closest are Garachico, Icod de los Vinos and Puerto de la Cruz. Teide, Pico Viejo and Montaña Blanca form the Central Volcanic Complex of Tenerife.
List of islands in the Atlantic Ocean in the context of Province of Santa Cruz de Tenerife
Province of Santa Cruz de Tenerife, also Province of Santa Cruz (Spanish: Provincia de Santa Cruz de Tenerife), is a province of Spain, consisting of the western part of the autonomous community of the Canary Islands. It consists of about half of the Atlantic archipelago: the islands of Tenerife, La Gomera, El Hierro, and La Palma. It occupies an area of 3,381 km (1,305 sq mi). It also includes a series of adjacent roques (those of Salmor, Fasnia, Bonanza, Garachico and Anaga).
Its capital is the city of Santa Cruz de Tenerife (commonly known as Santa Cruz), on the island of Tenerife (Spain's most populous island). At the start of 2023 the province had 1,067,173 inhabitants and a density of 315.6 /km, making it the province of Spain with the sixth highest population density, higher than that of the province of Las Palmas (the eastern half of the Canary Islands). 19.6% live in the capital, Santa Cruz de Tenerife, which is also the capital of the Autonomous Community of the Canary Islands. There are 54 municipalities in the province; see List of municipalities in Santa Cruz de Tenerife. Tenerife is the most populated island of the Canary Islands and most populous island of Spain. In addition, the island also has the highest altitude of Spain and all of the Atlantic Islands (Teide 3718 m).
