List of islands in the Pacific Ocean
The islands in the Pacific Ocean are categorized into three major island groups: Melanesia, Micronesia, and Polynesia. Depending on the context, the term Pacific Islands may refer to one of several concepts: those Pacific islands whose people have Austronesian origins, the Pacific islands once or currently colonized after 1500 CE, the geographical region of Oceania, or any island located in the Pacific Ocean.
This list of islands in the Pacific Ocean is organized by archipelago or political boundary. In order to keep this list of moderate size, the more complete lists for countries with large numbers of small or uninhabited islands have been hyperlinked.
Name ambiguity and groupings
A commonly applied biogeographic definition includes islands with oceanic geology that lie within Melanesia, Micronesia, Polynesia and the eastern Pacific. These are usually considered to be the "Tropical Pacific Islands". In the 1990s, ecologists Dieter Mueller-Dombois and Frederic Raymond Fosberg broke the Tropical Pacific Islands up into the following subdivisions:- Western Melanesia
- * The Bismarck Archipelago and other islands directly east of New Guinea
- * Bougainville and Buka Island
- * The Solomon Islands
- Eastern Melanesia
- * The Santa Cruz Islands
- * Vanuatu
- * New Caledonia
- * Fiji
- Subtropical islands in the Australia/New Zealand region
- * Lord Howe Island
- * Norfolk Island
- Micronesia
- * The Bonin Islands and Volcano Islands
- * Marcus Island
- * The Northern Marianas
- * The Southern Marianas
- * The Caroline Islands
- * Nauru and Banaba
- * Wake Island
- * Palau
- * The Marshall Islands
- * The Gilbert Islands
- Central Polynesia
- * Johnston Atoll
- * The Phoenix Islands
- * The Line Islands
- * Howland Island, Baker Island, Jarvis Island, Malden Island and Starbuck Island
- * Tuvalu, Tokelau and the Northern Cook Islands
- Western Polynesia
- * Tonga
- * Samoan Islands
- * Wallis and Futuna
- * Niue
- Eastern Polynesia
- * The rest of the Cook Islands
- * The Austral Islands
- * The Society Islands
- * The Tuamotu Archipelago and the Pitcairn Islands
- * Easter Island and Salas y Gómez
- * The Marquesas Islands
- Northern Polynesia
- * The Hawaiian Islands
- Oceanic islands of the Eastern Pacific
- * The Revillagigedo Islands
- * Cocos Island and Malpelo Island
- * Clipperton Island
- * The Galápagos Islands
- * The Desventuradas Islands
- * The Juan Fernández Islands
Geopolitics and Oceania grouping
Since the beginning of the 19th century, Australia and the islands of the Pacific have been grouped by geographers into a region called Oceania. It is often used as a quasi-continent, with the Pacific Ocean being the defining characteristic. In some countries, such as Argentina, Brazil, China, Chile, Costa Rica, Ecuador, France, Greece, Italy, Mexico, the Netherlands, Peru, Spain, Switzerland or Venezuela, Oceania is seen as a proper continent in the sense that it is "one of the parts of the world". In his 1879 book Australasia, British naturalist Alfred Russel Wallace commented that, "Oceania is the word often used by continental geographers to describe the great world of islands we are now entering upon" and that "Australia forms its central and most important feature." 19th century definitions encompassed the region as beginning in the Malay Archipelago, and as ending near the Americas. In the 19th century, many geographers divided up Oceania into mostly racially-based subdivisions; Australasia, Malaysia, Melanesia, Micronesia and Polynesia. The 1995 book The Pacific Island States, by Australian author Stephen Henningham, claims that Oceania in its broadest sense "incorporates all the insular areas between the Americas and Asia." In its broadest possible usage, it could include Australia, the Melanesian, Micronesian and Polynesian islands, the Japanese and Malay Archipelagos, Taiwan, the Ryukyu and Kuril Islands, the Aleutian Islands and isolated islands off Latin America such as the Juan Fernández Islands. Islands with geological and historical ties to the Asian mainland are rarely included in present definitions of Oceania, nor are non-tropical islands to the north of Hawaii. The 2004 book The Making of Anthropology: The Semiotics of Self and Other in the Western Tradition, by Jacob Pandian and Susan Parman, states that "some exclude from Oceania the nontropical islands such as Ryukyu, the Aleutian islands and Japan, and the islands such as Formosa, Indonesia and the Philippines that are closely linked with mainland Asia. Others include Indonesia and the Philippines with the heartland of Oceania."
Certain anthropological definitions restrict Oceania even further to only include islands which are culturally within Melanesia, Micronesia and Polynesia. Conversely, Encyclopedia Britannica believe that the term Pacific Islands is much more synonymous with Melanesia, Micronesia and Polynesia, and that Oceania, in its broadest sense, embraces all the areas of the Pacific which do not fall within Melanesia, Micronesia and Polynesia. The World Factbook and the United Nations categorize Oceania/the Pacific area as one of the seven major continental divisions of the world, and the two organizations consider it to politically encompass American Samoa, Australia, Christmas Island, Cocos Islands, the Cook Islands, Federated States of Micronesia, French Polynesia, Fiji, Guam, Kiribati, the Marshall Islands, Nauru, New Caledonia, New Zealand, Niue, Norfolk Island, the Northern Mariana Islands, Palau, Papua New Guinea, Pitcairn Islands, Samoa, the Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu, Wallis and Futuna and the United States Minor Outlying Islands.
Since the 1950s, many have viewed Australia as a continent-sized landmass, although they are still sometimes viewed as a Pacific Island, or as both a continent and a Pacific Island. Australia is a founding member of the Pacific Islands Forum, which is now recognized as the main governing body for the Oceania region. It functions as a trade bloc and deals with defense issues, unlike with the Pacific Community, which includes most of the same members. By 2021, the Pacific Islands Forum included all sovereign Pacific Island nations, such as Federated States of Micronesia, Fiji and Tonga, in addition to dependencies of other nations, such as American Samoa, French Polynesia and Guam. Islands which have been fully integrated into other nations, including Easter Island and Hawaii, have also shown interest in joining. Tony deBrum, Foreign Minister for the Marshall Islands, stated in 2014, "Not only is Australia our big brother down south, Australia is a member of the Pacific Islands Forum and Australia is a Pacific island, a big island, but a Pacific island." Japan and certain nations of the Malay Archipelago have representation in the Pacific Islands Forum, but none are full members. The nations of the Malay Archipelago have their own regional governing organization called ASEAN, which includes mainland Southeast Asian nations such as Vietnam and Thailand. In July 2019, at the inaugural Indonesian Exposition held in Auckland, Indonesia launched its 'Pacific Elevation' program, which would encompass a new era of elevated engagement with the region, with the country also using the event to lay claim that Indonesia is culturally and ethnically linked to the Pacific islands. The event was attended by dignitaries from Australia, New Zealand and some Pacific island countries.
