List of countries bordering on two or more oceans

Some non-landlocked countries touch more than one of the five named oceans: the Arctic, Atlantic, Indian, Pacfic, and Southern.^[1] Countries bordering only one ocean are not listed here, no matter how many of its marginal seas they touch.^[2] The main list includes only contiguous areas touching multiple oceans; a second list includes countries whose total number of oceans is increased due to discontiguous areas.

World map of countries by number of oceans bordered:

  landlocked countries;

  countries bordering one ocean;

  countries bordering two oceans;

  countries bordering three oceans;

  countries bordering several oceans via their dependent territories.

Contiguous area

This list includes only contiguous parts of a country with coastlines on multiple oceans. Countries touching multiple oceans due to discontiguous reasions are listed below in § Discontiguous countries. Under each ocean is listed the smallest named region or marginal sea that includes the coastline where that country and ocean meet.

Discontiguous countries

This section lists countries whose overall count of oceans is increased by considering discontiguous areas.

Only the largest contiguous area is listed under a given ocean, and then only if it contributes to the total number of oceans, so Great Britain and Metropolitan France are listed but not The Bahamas or French Guiana, and Alaska and the Lower 48 are listed separately, but not Hawaii.

Country	Counts		Pacific Ocean	Atlantic Ocean	Indian Ocean	Southern Ocean	Arctic Ocean
France	4	1	New Caledonia	Metropolitan France	Réunion	Adélie Land
UK	4	1	Pitcairn Islands	Great Britain	BIOT	British Antarctic Territory
US	3	2	Lower 48	Lower 48
		2	Alaska				Alaska

Notes

1. South Africa borders on three oceans if the Southern Ocean is considered to extend to its shores, but only on two otherwise.
2. Iceland bordrers on two oceans if the Greenland Sea is considered a part of the Arctic Ocean, but only one if it is considered a part of the North Atlantic.
3. Greenland is a part of the Kingdom of Denmark.
4. Although Alaska and the Lower 48 each borders on two oceans, no single contiguous U.S. territory borders on three oceans. The two together would make the United States a country bordering on three oceans.
5. The boundary between North America and South America is somewhat arbitrary. Although atlases in the Western countries today generally show Panama entirely within North America, some atlases show the continental boundary along the Panama Canal instead. Furthermore, some 19th century atlases even showed the continental boundary along the border between Costa Rica and Panama, which was then a part of Gran Colombia.^[3]
6. Chile borders on three oceans if the Southern and Atlantic Oceans are considered to meet in its territory, but only on two otherwise.
7. Argentina's oceans include the Southern Ocean if the Drake Passage is considered part of it and the Pacific Ocean if its waters are considered to extend to the Argentine portion of the Beagle Channel.
8. Australia borders on three oceans if the Southern Ocean is considered to extend that far north, but only on two otherwise.
9. Antarctica is included on this list although not a country. If the Southern ocean is considered a separate ocean, it borders on only that one ocean. If, however, the Southern Ocean is considered to be merely part of the Pacific, Atlantic, and Indian oceans, Antarctica borders on all three.
