This is a list of [[country|countries]] with [[territory]] that straddles more than one [[continent]], known as '''transcontinental states''' or '''intercontinental states'''.<ref name=":0">{{Cite web|title=Transcontinental Countries Of The World|url=https://www.worldatlas.com/articles/which-are-the-transcontinental-countries-of-our-world.html|access-date=2021-05-31|website=WorldAtlas|date=7 May 2021|archive-date=2021-05-14|archive-url=https://web.archive.org/web/20210514184932/https://www.worldatlas.com/articles/which-are-the-transcontinental-countries-of-our-world.html|url-status=live}}</ref>

'''Contiguous''' transcontinental countries are states that have one continuous or immediately-adjacent piece of territory that spans a [[boundaries between the continents|continental boundary]], most commonly the line that separates Asia and Europe. By contrast, '''non-contiguous''' transcontinental countries are those states that have portions of territory that are separated from one another either by a body of water or by other countries (such as in the case of France). Most non-contiguous transcontinental countries are countries with [[dependent territory|dependencies]] like United Kingdom with its [[British overseas territory|overseas territories]], but can be countries that have fully integrated former dependencies in their central states like France with its [[overseas departments and regions of France|overseas regions]].<ref name=":0" />

For the purposes of this article, a [[Continent#Number|seven-continent model]] is assumed based on common terms of reference by English language geographers.<ref name="NatlGeo">{{cite web|title=Continent|url=https://www.nationalgeographic.org/encyclopedia/continent/|access-date=5 February 2019|website=[[National Geographic Society|NationalGeographic.org]]|publisher=[[National Geographic]]|archive-date=16 July 2019|archive-url=https://web.archive.org/web/20190716045120/https://www.nationalgeographic.org/encyclopedia/continent/|url-status=dead}}</ref> Combined continents like "the Americas" and "Eurasia" are not acknowledged or referenced. The [[Boundaries between the continents#Asia and Europe|boundary between Asia and Europe]] is largely conventional (much of it over land), and several conventions remained in use well into the 20th century. However, the now-prevalent convention—which has been in use by some [[cartography|cartographers]] since about 1850—follows the [[Caucasus]] northern chain, the [[Ural (river)|Ural River]] and the [[Ural Mountains]], is used for the purposes of this list.<ref>The question was treated as a "controversy" in British geographical literature until at least the 1860s, with [[Douglas Freshfield]] advocating the Caucasus crest boundary as the "best possible", citing support from various "modern geographers" ([https://books.google.com/books?id=ips8AAAAIAAJ&pg=PA71 Journey in the Caucasus] {{Webarchive|url=https://web.archive.org/web/20230703174813/https://books.google.com/books?id=ips8AAAAIAAJ&pg=PA71 |date=2023-07-03 }}, ''Proceedings of the Royal Geographical Society'', Volumes 13–14, 1869). In 1958, the Soviet Geographical Society formally recommended that the boundary between Europe and Asia be drawn in textbooks from [[Baydaratskaya Bay]], on the [[Kara Sea]], along the eastern foot of the Ural Mountains, then the Ural River to the [[Mugodzhar Hills]], the [[Emba River]], and the Kuma–Manych Depression (i.e. passing well north of the Caucasus); {{cite web |url=http://velikijporog.narod.ru/st_evraz_gran.htm |title=Do we live in Europe or in Asia? |language=ru |access-date=2015-11-26 |archive-date=2018-02-18 |archive-url=https://web.archive.org/web/20180218073322/http://velikijporog.narod.ru/st_evraz_gran.htm |url-status=live }}; {{cite web |url=http://www.i-u.ru/biblio/archive/orlenok_fisicheskaja/06.aspx |title=Physical Geography |year=1998 |author=Orlenok V. |language=ru |url-status=dead |archive-url=https://web.archive.org/web/20111016212930/http://www.i-u.ru/biblio/archive/orlenok_fisicheskaja/06.aspx |archive-date=2011-10-16 }}. Nevertheless, most Soviet-era geographers continued to favour the boundary along the Caucasus crest. (E. M. Moores, R. W. Fairbridge, ''Encyclopedia of European and Asian regional geology'', Springer, 1997, {{ISBN|978-0-412-74040-4}}, p. 34: "most Soviet geographers took the watershed of the Main Range of the Greater Caucasus as the boundary between Europe and Asia.")</ref> This convention results in several countries such as in the case of [[Azerbaijan]], [[Kazakhstan]], and [[Turkey]] finding themselves almost entirely in 'Asia', with a few small [[enclave and exclave|enclaves]] or districts technically in 'Europe'. Notwithstanding these anomalies, this list of transcontinental or intercontinental states respects the convention that Europe and Asia are full continents rather than [[subcontinent]]s or component [[landmass]]es of a larger [[Eurasia]]n continent.

Listed further below, separately, are countries with distant non-contiguous parts (overseas territories) on separate continents.

**Non-contiguous transcontinental states are those that have portions of territory that are separated from one another either by a significant [[body of water]] or by other land.<ref name="WorldAtlas" /><ref name="SciTrends" /> Most non-contiguous transcontinental countries are countries with [[Territory#Overseas territory|overseas territories]].<ref name=":0" />

The [[boundaries between the continents]] can be vague and subject to interpretation, making it difficult to conclusively define what counts as a 'transcontinental state'.

*For the purposes of this article, a [[Continent#Number|seven-continent model]] is assumed.<ref name="NatlGeo" />

**Therefore, states that have territory across sub-continental boundaries, as well as [[Plate tectonics#Types of plate boundaries|plate boundaries]] that are only internal to continents, are excluded from this article.

*Some non-contiguous transcontinental states have territory situated on distant islands that may or may not be considered a part of another nearby continent (e.g. [[Yemen]]'s [[Socotra]] and Portugal's [[Madeira]]). Though there is debate{{citation needed|date=November 2020}} as to whether these states ought to be considered 'transcontinental', they are still included in this article.

*States that only have [[uninhabited island]] territories as parts of another continent (e.g., [[Venezuela]]'s [[Isla de Aves|Aves Island]]) are considered transcontinental for the purpose of this article.{{citation needed|date=November 2020}}

*While it is debatable as to whether states that have claimed territory within the [[Antarctic Treaty System]] can have actual control of that claimed territory (e.g., [[Chilean Antarctic Territory]]), they are included in this article.

*Some [[autonomous administrative division|autonomous region]]s (or [[dependent territory|dependent territories]]) may be constitutionally distinguishable from the parent state that claims them as their territory (e.g., in the case of [[British Overseas Territories]] and the United Kingdom), thereby causing debate as to whether such states ought to be considered 'transcontinental'.{{citation needed|date=November 2020}} They are nevertheless included in this article.

**[[Micronation]]s, [[autonomous administrative division|autonomous regions]], and [[administrative division|subnational entities]] that are in themselves transcontinental are excluded from the lists in this article as a separate entry from their controlling state.

*Any entry must be a [[member states of the United Nations|UN member state]] or a part of the [[United Nations System]]. Therefore, [[list of states with limited recognition|states with limited recognition]] are excluded from the lists in this article.

Contiguous transcontinental states are those countries that have one continuous or immediately adjacent piece of territory that spans a [[boundaries between the continents|continental boundary]]. More specifically, they contain a portion of their territory on one continent and a portion of their territory on another continent, while having these two portions connected via a natural geological land connection (e.g. Russia) or the two portions being immediately adjacent to one another (e.g. Turkey).<ref name="WorldAtlas" /><ref name="SciTrends" /> In other words, someone can travel to another continent without changing the country (without crossing a border).

=== Africa and Asia ===

The modern convention for the land boundary between Asia and Africa runs along the [[Isthmus of Suez]] and the [[Suez Canal]] in [[Egypt]]. The border continues through the [[Gulf of Suez]], [[Red Sea]], and [[Gulf of Aden]]. In antiquity, Egypt had been considered part of Asia,{{citation needed|date=February 2023}} with the ''[[Catabathmus Magnus]]'' escarpment taken as the boundary with [[Ancient Libya|Africa (Libya)]].

* {{Flag|Egypt}}: Out of the 27 [[governorates of Egypt]], two lie entirely on the Asian [[Sinai Peninsula]] and two are transcontinental: [[Ismailia Governorate]] is nearly equally divided by the Suez Canal, and [[Suez Governorate]]—which is coterminous with the "transcontinental city" of [[Suez]]—has a small portion east of the Canal.

The conventional [[Boundaries between the continents#Asia and Europe|Asia-Europe boundary]] was subject to considerable variation during the 18th and 19th centuries, indicated anywhere between the [[Don (river)|Don River]] and the [[Caucasus]] to the south or the [[Ural Mountains]] to the east. Since the late 19th century, the Caucasus–Urals boundary has become almost universally accepted. According to this now-standard convention, the boundary follows the [[Aegean Sea]], the [[Turkish Straits]], the [[Black Sea]], along the [[Drainage divide|watershed]] of the [[Greater Caucasus]], the northwestern portion of the [[Caspian Sea]] and along the [[Ural (river)|Ural River]] and [[Ural Mountains]] to the [[Arctic Ocean]].<ref name="NatlGeoAtlas">{{Cite book|title=National Geographic Atlas of the World|edition=9th|year=2011|location=Washington, D.C.|publisher=[[National Geographic Society|National Geographic]]|isbn=978-1-4262-0634-4|at="Europe" (plate 59); "Asia" (plate 74) |quote=A commonly accepted division between Asia and Europe ... is formed by the Ural Mountains, Ural River, Caspian Sea, Caucasus Mountains, and the Black Sea with its outlets, the Bosporus and Dardanelles.}}</ref><ref name="Factbook">{{Cite book | title=World Factbook | date=22 March 2022 | url=https://www.cia.gov/the-world-factbook/countries/azerbaijan/ | location=Washington, D.C. | publisher=[[Central Intelligence Agency]] | access-date=24 January 2021 | archive-date=27 January 2021 | archive-url=https://web.archive.org/web/20210127171042/https://www.cia.gov/the-world-factbook/countries/azerbaijan/ | url-status=live }}</ref>

According to this convention, the following countries have territory in both Asia and Europe.

* {{Flag|Azerbaijan}} is a country located mainly on the [[Transcaucasia|Asian portion]] of the [[Caucasus]], with a small portion of the country, its [[Qusar District|Qusar]], [[Shabran District|Shabran]], [[Siazan District|Siazan]], [[Khachmaz District|Khachmaz]] and [[Quba District (Azerbaijan)|Quba]] districts north of the [[Greater Caucasus#Watershed|Greater Caucasus Watershed]], and thus in Europe, placing a population of about half a million (or c. 5% of the country's total population) in Europe.
* {{Flag|Georgia}} is located mainly on the [[Transcaucasia|Asian portion]] of the [[Caucasus]]; however, the Municipality of [[Kazbegi Municipality|Kazbegi]], north [[Khevsureti]] and [[Tusheti]] are located north of the Greater Caucasus Watershed, which is geographically in Europe, with mountain peaks throughout the Caucasus ridge, placing around 5% of the country's total territory in Europe.

* {{Flag|Colombia}}: Most of the Colombian mainland is located in northern South America (see [[#North America and South America|North America and South America]] above) and the [[Malpelo Island]] in the Pacific Ocean is also associated with South America (or on rare occasion Oceania, due to its status as an [[oceanic island]]).<ref name="ling"/><ref name="zug"/> However, the state also administers the [[Archipelago of San Andrés, Providencia and Santa Catalina|San Andrés and Providencia]] [[archipelago]], {{convert|640|km|mi}} WNW of Colombia's [[Caribbean Region, Colombia|Caribbean Coast]], in North America.
* {{Flag|Venezuela}} ([[Isla de Aves|Aves Island]]): Most of Venezuela, predominantly its mainland, is located in northern South America. Aves Island, however, is geographically a definitive part of North America. It is one of the [[Federal Dependencies of Venezuela]] which are under the administration of the [[Ministry of Interior, Justice and Peace (Venezuela)|Ministry of Interior, Justice and Peace]].
The special case of Caribbean islands adjacent to the South American coastline:
* {{Flag|Trinidad and Tobago}}: The state of Trinidad and Tobago lies on two [[List of tectonic plates|tectonic plates]]. The southern half of [[Trinidad]] lies on the [[South American Plate]] while the northern half of Trinidad and the island of [[Tobago]] lie on the [[Caribbean Plate]]. However, these geological features do not necessarily qualify Trinidad and Tobago as a transcontinental state, as the whole territory is often labeled [[geopolitics|geopolitically]] as part of North America.
* ''[[Leeward Antilles]]'' (Collectively [[Aruba]], [[Bonaire]], and [[Curaçao]] of the Netherlands; [[Nueva Esparta]] of [[Venezuela]]; and the [[Federal Dependencies of Venezuela]], excluding [[Isla de Aves|Aves Island]]): The Caribbean islands division of North America and South America is complicated. [[geopolitics|Geopolitically]], all Caribbean islands in the [[West Indies]] are often labeled as North American islands, but [[geology|geologically]], the islands of the Leeward Antilles lie on the [[continental shelf]] of South America, and can be considered South American as well. Excluding the geographically North American Aves Island, the remaining Venezuelan islands of the Federal Dependencies are islands situated in the Caribbean on the continental shelf of South America. These islands are north of the Venezuelan mainland and are akin to the location of Aruba, Bonaire, Curaçao, and Trinidad and Tobago.

Essentially we have followed the limits established by Meyer de Schauensee (1970: xii) with a few minor modifications. Thus, all the continental inshore islands ''are'' included (e.g., Trinidad and Tobago; various small islands off the northern coast of Venezuela, the Netherlands Antilles [Aruba, Bonaire and Curaçao]; and Fernando de Noronha, off the northeastern coast of Brazil), but islands more properly considered part of the West Indies (e.g. Grenada) are ''not''. To the south, we have opted to include the Falkland Islands (or Islas Malvinas — in referring to them as the Falklands we are not making any political statement but merely recognizing that this book is being written in the English language), as their avifauna is really very similar to that of Patagonia and Tierra del Fuego. However, various other islands farther out in the South Atlantic (e.g., South Georgia) are not included except incidentally (e.g., endemic South Georgia Pipit have been incorporated). Likewise, the Juan Fernández Islands far off the Chilean coast have not been included (except for incidental comments), nor have the Galápagos Islands, situated even further off the Ecuadorian coast. |archive-date=3 July 2023 |archive-url=https://web.archive.org/web/20230703174814/https://books.google.com/books?id=tRBb15pk4w0C&dq=%22SOUTH+GEORGIA%22+%22PART+OF+SOUTH+AMERICA%22&pg=PA14 |url-status=live }}</ref>
