List of countries bordering on two or more oceans
This is a list of countries which border two or more oceans, including both sovereign states and dependencies, provided the same contiguous territory borders on more than one of the five named oceans, the Pacific, Atlantic, Indian, Southern, and Arctic. Countries which border on multiple oceans because of discontiguous regions are excluded here but included in the list of transcontinental countries.
- ^ South Africa borders on three oceans if the Southern Ocean is considered to extend to its shores, but only on two otherwise.
- ^ Greenland is part of Denmark.
- ^ a b Although Alaska and the Lower 48 each border on two oceans, no single contiguous US territory borders on three oceans.
- ^ The boundary between North and South America is somewhat arbitrary. Although atlases today generally show Panama entirely within North America, some atlases showed the continental boundary along the Panama Canal. Furthermore, some 19th century atlases even showed the continental boundary along the border between Costa Rica and Panama, which was then part of Gran Colombia.
- ^ Chile borders on three oceans if the Southern and Atlantic Oceans are considered to meet in its territory, but only on two otherwise.
- ^ Argentina borders on three oceans if the Drake Passage and Strait of Magellan is counted as part of the Southern Ocean, but only on one if it is considered part of the South Pacific and the South Atlantic.
- ^ Australia borders on three oceans if the Southern Ocean is considered to extend that far north, but only on two otherwise.
- ^ 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.
