List of islands by area
This list of islands by area includes all islands in the world larger than 2,500 km2 (970 sq mi) and most of the islands over 1,000 km2 (390 sq mi), sorted in descending order by area. For comparison, four very large continental landmasses are also shown.
Continental landmasses are not usually classified as islands despite being completely surrounded by water.[Note 1] However, because the definition of continent varies between geographers, the Americas is sometimes defined as two separate continents while mainland Australia is sometimes defined as an island as well as a continent. Nevertheless, for the purposes of this list, mainland Australia along with the other major landmasses have been listed as continental landmasses for comparison. The figures are approximations and are for the four major continental landmasses only.[Note 2] The artificial Panama and Suez canals are disregarded, as they are not natural waters that separate the continents.
|Rank||Continental landmass[Note 3]||Area
|1||Africa-Eurasia||79,810,726[Note 4]||30,815,094||126 countries,[Note 8] 9 de facto states,[Note 10] 2 overseas autonomous cities of Spain,[Note 11] Peñón de Vélez de la Gomera,[Note 12] Hong Kong,[Note 13] Macau,[Note 14] and Gibraltar[Note 15]|
|2||America (continent)||37,699,623[Note 16]||14,555,906||22 countries[Note 18] and French Guiana[Note 19]|
|3||Antarctica[Note 20]||12,272,800[Note 21]||4,738,600||None[Note 23]|

Islands 100,000 km2 (38,600 sq mi) and greater
Islands 25,000–99,999 km2 (9,700–38,600 sq mi)
Islands 10,000–24,999 km2 (3,861–9,652 sq mi)
Islands 5,000–9,999 km2 (1,931–3,861 sq mi)
Islands 2,500–4,999 km2 (965–1,930 sq mi)
Islands 1,000–2,499 km2 (386–965 sq mi)
This section of the list might not be complete but covers almost all of the islands in the world over 1,000 km2 (390 sq mi). The area of some Antarctic islands is uncertain.

- The United States Geological Survey is a notable exception. The United States-based scientific agency considers all landmasses surrounded by ocean water, including continental mainlands, as islands. Under their definition, Africa, Australia, Eurasia, North America, and South America are classified as continental mainland islands.
- Physiographically, there are only four continents (including offshore continental islands which sit on the nearby continental shelves) that are completely surrounded by water: Afro-Eurasia (57% of the global land area), the Americas (28.5%), Antarctica (9%), and Australia (5%). The remaining 0.5% is made up of remote oceanic islands, mostly scattered within Oceania in the central and south Pacific Ocean.
- Including landmasses which are above water and over 2,500,000 km2. The submerged continent of Zealandia (approx. 5,000,000 km2) is excluded.
- Figure derived from the Global Islands Explorer website, by adding the areas of mainland Africa (29,370,907 km2) and mainland Eurasia (50,439,819 km2).
- Egypt has a small portion of its land located on mainland Eurasia. Equatorial Guinea's capital city is located on an island.
- Azerbaijan, Georgia, Kazakhstan, and Turkey each have a small portion of their land located on continental Europe. Malaysia has a significant portion of its land located on islands.
- Russia has a big portion of its land located on continental Asia. Denmark's capital city is located on an island.
- 48 countries on mainland Africa[Note 5] and 78 countries on mainland Eurasia (38 countries on continental Asia[Note 6] and 40 countries on continental Europe[Note 7]).
- Abkhazia and South Ossetia are both located south of the Greater Caucasus watershed and thus geographically parts of Asia.
- 2 states on mainland Africa and 7 states on mainland Eurasia (3 states on continental Asia[Note 9] and 4 states on continental Europe).
- Ceuta and Melilla, both located on mainland Africa.
- A Spanish overseas tied island on mainland Africa, politically a part of the plazas de soberanía.
- A special administrative region of China. Except Hong Kong Island and the Outlying Islands, the rest of the territory is located on continental Asia.
- A special administrative region of China whose historical and population core, the Macau Peninsula, is located on continental Asia
- A British overseas territory, located on continental Europe.
- Figure derived from the Global Islands Explorer website, by adding the areas of mainland North America (20,090,075 km2) and mainland South America (17,609,548 km2).
- Depending on the definition, a significant portion of Panama (land east of the Panama Canal) could be considered a part of mainland South America.
- 10 countries on mainland North America[Note 17] and 12 countries on mainland South America.
- An overseas department and region of France, located on mainland South America.
- Antarctica is a special case, for if its ice is considered not as land, but as water, it is not a single landmass, but several landmasses of much smaller area, since the ice-bedrock boundary is below sea level in many regions of the continent. If its ice cover were to be lifted, some rock that is currently below sea level would rise as the weight of the ice would be removed, although this would in part be counteracted, and in some areas of the continent overtaken, by eustatic rises in sea level.
- Area of mainland Antarctica, without the ice shelves and nearby islands.
- All territorial claims in Antarctica are in abeyance under the Antarctic Treaty System.
- 7 countries have made 8 territorial claims.[Note 22]
- Mainland Australia is more than three times the size of Greenland, the largest island. Australia is sometimes dubbed "The Island Continent" or "Earth's largest island, but its smallest continent".
- Figure derived from the Geoscience Australia website, the area of mainland Tasmania (64,519 km2) has been deducted. The Global Islands Explorer website has given a slightly larger figure of 7,618,696 km2 for the area of mainland Australia.
