Transcontinental nation

This is a list of countries spanning more than one continent, known as transcontinental states.[dubious ] While there are many countries with non-contiguous overseas territories fitting this definition, only a limited number of countries have territory spanning an overland continental boundary:

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

Contiguous boundary

Africa and Asia

For more details about the geographical border between Africa and Asia, see Boundaries between continents.

The land border between Asia and Africa is considered to go 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.


Two of 27 governorates of Egypt 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.

Asia and Europe

For more details about the geographical border between Europe and Asia, see Borders of the continents.

The modern definition of Europe (e.g. National Geographic Society) has the Europe-Asia boundary follow the watershed of the Ural Mountains to the source of the Ural River, then follows that river to the Caspian Sea. The border then follows the Greater Caucasus watershed from the Caspian Sea to the Black Sea. According to this mainstream definition, there are five states with territory across the continental boundary:

  • Russia: with most of its population situated in Europe, has significant territory in Central and Northern Asia (Siberia in the Russian Far East). About 75% of the Russian population lives in the European part.
  • Turkey: mostly situated in Asia Minor, with some territory in Southeastern Europe (Turkish Thrace). About 88% of the Turkish population lives in the Asian part.
  • Kazakhstan: mostly situated in Central Asia, with the western parts of two of its provinces west of the Ural River in Europe. About 96% of the Kazakh population lives in the Asian part.
  • Azerbaijan: primarily situated in Transcaucasia, with five northeastern districts ("rayons") in European Ciscaucasia, north of the Greater Caucasus watershed. About 98% of the Azerbaijani population lives in Transcaucasia.
  • Georgia: primarily situated in Transcaucasia, with a small area just north of the Greater Caucasus watershed. More than 99% of the Georgian population lives in Transcaucasia.

A convention in Russian geography draws the continental boundary along the Manych River to the Caspian, excluding Georgia and Azerbaijan from transcontinental status. A historical convention used in the 19th century followed the lower Volga instead of the Ural river, which would also exclude Kazakhstan from being transcontinental.


The northeastern Azerbaijan district borders run mostly along the main Caucasus watershed. Five districts are entirely within Europe, and the transcontinental Khizi district is almost equally divided on the two sides of the watershed. Azerbaijan is a member of the Council of Europe.


The Terek and Sulak rivers both originate in Georgia and both empty into the Caspian Sea in Dagestan; their upper basins in Georgia are north of the Greater Caucasus watershed (the modern-day Europe-Asia divide), including northern parts of the Tusheti and Khevsureti historical regions and Kazbegi District. A total of 2,650 square kilometers, or 4% of Georgia's territory, is north of the Caucasus Mountains and thus in Europe.


Kazakhstan's provincial borders do not follow the Ural River, although some of its western district borders do so. Two of the provinces are transcontinental, Atyrau Province and West Kazakhstan Province. The capital of the former, Atyrau, is split by the mouth of the Ural and is a transcontinental city. Almost all of it is in Asia with a small portion in Europe. Two of Atyrau Province's districts are entirely in Europe, three of its districts are entirely in Asia, and its Inderskiy and Makhambetskiy districts are transcontinental.[1] Five of West Kazakhstan's districts and the province's capital city of Oral are entirely in Europe, five of its districts are entirely in Asia, and its Akzhaikskiy district is transcontinental.[2]


Russian regions' borders follow the continental divide (Ural Mountains and Ural River) more often than not. There is also the relatively small 2600 square kilometer Sochi area of Russia in Asia, bordering Georgia and located south of the main Caucasus watershed. Orenburg on the Ural River is a transcontinental city. More detail on the political divisions through which the intercontinental boundary runs can be found here. Russia is a member of the Council of Europe.


Main article: Turkish Thrace

Three of Turkey's provinces (Edirne, Kırklareli and Tekirdağ) are entirely in Europe while Çanakkale and Istanbul are transcontinental provinces. Three of Çanakkale's districts are entirely in Europe and its other nine districts are entirely in Asia. Nineteen of Istanbul's districts are entirely in Europe and its other twelve districts are entirely in Asia.

Europe and North America

  • Greenland: Greenland is a territory of Denmark, fully located on the North American tectonic plate and close to the mainland, and is considered to be geographically part of North America. Although it is politically associated with Europe and internationally represented by a European country (including in the Council of Europe), it is largely autonomous. Historically and ethnically, its native population is of American tradition, although it also shares cultural links with other native peoples bordering the Arctic Sea in Northern Europe and Asia (today in Norway, Sweden, Finland and Russia), as well as in North America (Alaska in the U.S., Northwest Territories and Nunavut in Canada). Greenland was part of the Danish territory and within the territory of the European Union, but voted for a larger autonomy and is now excluded from it.
  • Iceland: Iceland is on the fracture line splitting the Northern Atlantic Ocean between the North American plate and the Eurasian plate. Measuring to the North American island of Greenland, Iceland is much closer to North America than it is to Europe; however it is over twice as close to mainland Europe than to mainland North America. Using a plate tectonics definition, Iceland would qualify as a transcontinental country ; however, "continents" are not defined by plate tectonics, and geographically, ethnically, historically, and culturally, Iceland is commonly considered to be European and not transcontinental. Iceland is a full member of the Council of Europe (but still not in the European Union, to which it could qualify).
  • The Netherlands are mostly in Europe. However, since the dissolution of the Netherlands Antilles on 2010-10-10, the country includes the three "special municipalities" of Bonaire, St. Eustatius and Saba (collectively known as the BES islands) in the Caribbean area.
  • Portugal: Continental Portugal is in Europe, while the Azores archipelago (also associated with Europe) has two islands (Corvo and Flores) that are part of the American plate (which makes it a tricontinental country, see Africa and Europe section below).

Europe, North America, South America, Oceania, and Africa

North America, Oceania and Asia

  • United States: While the territory of the United States lies overwhelmingly in North America, it includes the state of Hawaii in Oceania as well as other Oceanian island possessions and Alaskan islands on NE Asia's continental shelf.

North and South America

North American Caribbean islands belonging to South American countries:

Other examples

These examples have integral parts associated with other continents. Norway, South Africa, and the United Kingdom may also be considered transcontinental by virtue of their distant island possessions or territories associated with a continent other than where the country is based.

Antarctica: claims

A number of nations claim ownership over portions of the continent of Antarctica. Some, including Argentina and Chile, consider the Antarctic land they claim to be integral parts of their national territory. Some nations also have sub-Antarctic island possessions north of 60°S latitude and thus recognized by international law under the Antarctic Treaty System, which holds in abeyance land claims south of 60°S latitude.
