List of transcontinental countries

This is a list of countries located on more than one continent, known as transcontinental states or intercontinental states. While there are many countries with non-contiguous overseas territories fitting this definition, only a limited number of countries have territory straddling an overland continental boundary, most commonly the line that separates Europe and Asia.
The boundary between Europe and Asia is largely conventional, and several conventions remained in use well into the 20th century. However, the now-prevalent convention, used for the purposes of this list, follows the Caucasus northern chain, the Ural River and the Ural Mountains. It has been in use by some cartographers since about 1850. This convention results in several countries 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.
Criteria for inclusion.
The lists within this article include entries that meet the following criteria:
Exceptions:
Contiguous boundary.
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 Europe-Asia 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 later 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, Azerbaijan, Georgia, Kazakhstan, the Russian Federation, and the Republic of Turkey 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.
