The terms international waters or trans-boundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater systems (aquifers), and wetlands.

Oceans, seas, and waters outside of national jurisdiction are also referred to as the high seas or, in Latin, mare liberum (meaning free seas).

Ships sailing the high seas are generally under the jurisdiction of the flag state; (if there is one) however, when a ship is involved in certain criminal acts, such as piracy, any nation can exercise jurisdiction under the doctrine of universal jurisdiction.

International waterways

Several international treaties have established freedom of navigation on semi-enclosed seas.

• The Copenhagen Convention of 1857 opened access to the Baltic by abolishing the Sound Dues and making the Danish Straits an international waterway free to all military and commercial shipping.
• Several conventions have opened the Bosporus and Dardanelles to shipping. The latest, the Montreux Convention Regarding the Regime of the Turkish Straits, maintains the straits' status as an international waterway.

Other international treaties have opened up rivers, which are not traditionally international waterways.

• The Danube River is an international waterway so that landlocked Austria, Hungary, Serbia and Slovakia (and the southern parts of Germany, itself not landlocked) can have secure access to the Black Sea.

Disputes over International waters

See also: Territorial claims in the Arctic and Northwest Passage

See also: Australian Antarctic territorial waters

Current unresolved disputes over whether particular waters are "International waters" include:

• The Arctic Ocean: While Canada, Denmark, Russia and Norway all regard parts of the Arctic seas as national waters or internal waters, most European Union countries and the United States officially regard the whole region as international waters.^{[citation needed]}
• The Southern Ocean: Australia claims EEZ around its Antarctic territorial claim. Since this claim is only recognised by four other countries, the EEZ claim is also disputed.

In addition to formal disputes, the government of Somalia exercises little control de facto over Somali territorial waters. Consequently, much piracy, illegal dumping of waste and fishing without permit has occurred.
