Exclusive economic zones by country

United States

Alaska adds 3,682,912 km² and Hawaii 2,474,715 km², each more than the zone off the lower 48 states (2,450,909 km²). Most of the rest lies around small Pacific islands, such as the Northern Mariana Islands, Johnston Atoll and American Samoa. The zone around Wake Island (406,970 km²) is left out, because the Marshall Islands also claim it.

France

The zone around mainland France is only 348,474 km². French Polynesia's zone alone is 4,766,689 km², larger than the land area of the whole European Union. Clipperton, an uninhabited atoll off Mexico with 1.7 km² of land, adds 435,657 km². About 572,000 km² around islands that other countries also claim (Tromelin, Matthew and Hunter, Mayotte and the Glorioso Islands) is left out.

Australia

The mainland and Tasmania account for 6,873,830 km². Five remote islands and island groups, such as Macquarie Island and the Cocos (Keeling) Islands, make up the other 23.6%. Australia's Antarctic claim is not counted.

Russia

Russia's Arctic coastline is about 24,150 km long, 53% of the Arctic Ocean's coast. In February 2023 the UN continental shelf commission accepted that the Lomonosov Ridge under the Arctic Ocean is an extension of Russia's seabed. Denmark, for Greenland, and Canada claim overlapping seabed along the same ridge.

Indonesia

Indonesia is the world's largest archipelagic state: its geospatial agency counted 17,380 named islands in December 2024. On July 14, 2017 Indonesia renamed the northern part of its zone the "North Natuna Sea", where China's claim overlaps. China's foreign ministry called the renaming "totally meaningless".

New Zealand

New Zealand's own waters cover 4,104,551 km², and Tokelau adds 320,548 km². The Cook Islands (1,969,553 km²) and Niue (318,140 km²) govern themselves in free association with New Zealand and manage their own zones, so they are not counted here. In February 2025 the Cook Islands signed agreements with China, including on seabed minerals research, without consulting New Zealand. New Zealand paused NZ$18.2 million of aid in June 2025 and resumed its funding in April 2026.

United Kingdom

Pitcairn (842,291 km²) and Tristan da Cunha (758,168 km²) each give the UK more sea than the zone around Britain itself (727,260 km²). The Falklands (550,566 km²) and South Georgia and the South Sandwich Islands (1,237,783 km²) are left out, because Argentina also claims them. On September 3, 2026 Argentina's president, Javier Milei, announced sanctions on companies working in the Falklands' oil sector.

Japan

Japan's government puts its waters at about 4.47 million km², counting the waters it disputes around the Kuril Islands (with Russia), the Senkaku Islands (with China and Taiwan) and Liancourt Rocks (with South Korea). Okinotorishima, a reef 1,700 km south of Tokyo with two tiny islets above water at high tide, gives Japan about 400,000 km². China and South Korea say Okinotorishima is a rock, which under the law of the sea cannot have such a zone.

Kiribati

Kiribati's 33 islands have only 811 km² of land. They straddle the equator and the 180th meridian, and since January 1, 1995 the International Date Line has bent east around Kiribati so the whole country shares one date. Kiribati switched its diplomatic recognition from Taiwan to China on September 20, 2019.

Denmark

Greenland's zone is 2,268,623 km² and the Faroe Islands' 265,326 km². Denmark itself provides 104,229 km², 4% of the total. On September 22, 2026 the US, Denmark and Greenland signed a deal at the UN that confirms Greenland is part of the Kingdom of Denmark; the parliaments of Denmark and Greenland still have to approve it.

Norway

Svalbard adds 796,819 km² and Jan Mayen 292,907 km² to the mainland's 931,288 km². The 1920 Svalbard Treaty gives Norway sovereignty over Svalbard, but the other parties have equal rights to fish, hunt and mine there. In 1977 Norway declared a 200-mile Fisheries Protection Zone around Svalbard instead of an exclusive economic zone, and Russia calls that zone unlawful.

Mauritius

Marine Regions counts the Chagos Archipelago's zone (647,678 km²) for Mauritius. In 2019 the International Court of Justice advised that the UK should end its administration of the islands "as rapidly as possible". The UK and Mauritius signed a treaty on May 22, 2025 handing the islands to Mauritius, with the UK leasing the Diego Garcia military base for 99 years. As of September 2026 the treaty has not been ratified, and the UK still runs the islands.

Portugal

The Azores (960,421 km²) and Madeira (452,796 km²) make up 82% of Portugal's total. In 2009 Portugal asked the UN continental shelf commission to recognize about 2 million km² of seabed beyond 200 nautical miles. As of September 2026 the commission has not decided.

Ukraine

Marine Regions marks all of Ukraine's zone as also claimed by Russia since Russia's 2014 annexation of Crimea. The UN General Assembly (resolution 68/262) and this site's maps treat Crimea as part of Ukraine, so this ranking counts the zone for Ukraine.
