This is a list of countries with territory that straddles more than one continent, known as transcontinental states or intercontinental states. Contiguous transcontinental countries are states that have one continuous or immediately-adjacent piece of territory that spans a 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 dependencies like United Kingdom with its overseas territories, but can be countries that have fully integrated former dependencies in their central states like France with its overseas regions. For the purposes of this article, a seven-continent model is assumed based on common terms of reference by English language geographers. Combined continents like "the Americas" and "Eurasia" are not acknowledged or referenced. The 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 cartographers since about 1850—follows the Caucasus northern chain, the Ural River and the Ural Mountains, is used for the purposes of this list. 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" (Journey in the Caucasus, 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); ;. 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.") 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 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 subcontinents or component landmasses of a larger Eurasian continent. Listed further below, separately, are countries with distant non-contiguous parts (overseas territories) on separate continents.

Definition

The lists within this article include entries that meet the following criteria: The boundaries between the continents can be vague and subject to interpretation, making it difficult to conclusively define what counts as a 'transcontinental state'.

Contiguous boundary

Contiguous transcontinental states are those countries that have one continuous or immediately adjacent piece of territory that spans a 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). 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, with the Catabathmus Magnus escarpment taken as the boundary with Africa (Libya).

Asia and Europe

The conventional Asia-Europe boundary was subject to considerable variation during the 18th and 19th centuries, indicated anywhere between the 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 watershed of the Greater Caucasus, the northwestern portion of the Caspian Sea and along the Ural River and Ural Mountains to the Arctic Ocean. According to this convention, the following countries have territory in both Asia and Europe.

North America and South America

The conventional boundary between North America and South America is at some point on the Colombia–Panama border, with the most common demarcation in atlases and other sources following the Darién Mountains watershed where the Isthmus of Panama meets the South American continent (see Darién Gap). This area encompasses a large watershed, forest and mountains in the northern portion of Colombia's Chocó Department and Panama's Darién province. Some geographers prefer to use the Panama Canal as the physical boundary between North and South America instead. Under this convention, its capital Panama City is classified as a South American city. Given the competing claims, the Panamanian sports governing bodies affiliate to differing continental/regional confederations: its athletics federation to South America's, its soccer federation to North, Central America and Caribbean's; its Olympic committee to both South America's and Central America's.
