Nauru is a single-island country in the western Pacific Ocean, one of the smallest sovereign states on Earth at just 21 square kilometers. In June 2026 it formally notified the United Nations of a name change, becoming the Republic of Naoero, though “Nauru” remains the name most widely known internationally and is used throughout this article alongside the new official name.

Where Is Nauru Located?

Nauru sits in Micronesia, in the western Pacific, about 42 kilometers south of the Equator, with no land neighbors and no natural harbor. It is an isolated raised coral atoll, one of only three great phosphate rock islands in the Pacific, alongside Banaba (Kiribati) and Makatea (French Polynesia), according to the United Nations in Micronesia.

The Geography of a Raised Coral Island

The island’s shape is often described as roughly oval. A narrow coastal strip, only 150 to 300 meters wide, rings the island and holds most of the population and infrastructure. Behind it rises “Topside,” a central limestone plateau standing 40 to 60 meters above sea level, according to the UN Food and Agriculture Organization. Decades of open-cast phosphate mining left much of Topside stripped down to jagged limestone pinnacles, leaving only around 4 square kilometers of land fertile enough to farm, concentrated along the coast and around Buada Lagoon, a freshwater lake inland. The island has no rivers, is prone to drought, and depends on brackish groundwater and rainwater collection. A coral reef, studded with pinnacles, surrounds the entire coastline, according to the Government of the Republic of Nauru.

A Brief History of Nauru

From Isolated Island to Colonial Rule

Before sustained European contact, the island supported roughly 12 matrilineal clans, each led by a chief, according to Encyclopaedia Britannica. British sailors sighted the island in 1798, calling it “Pleasant Island,” but regular outside contact did not begin until whaling ships arrived in the 1830s. Germany annexed the island into its Marshall Islands protectorate in 1888. Phosphate rock, formed from ancient seabird droppings, was discovered around the turn of the century, and mining began in earnest in 1907 under the Pacific Phosphate Company, permanently reshaping the island’s economy and landscape.

War, Trusteeship, and Independence

Australia occupied Nauru during the First World War, and in 1920 it became a League of Nations mandate jointly administered by Australia, Britain, and New Zealand. Japanese forces occupied the island in 1942 and forcibly deported about 1,200 Nauruans to Chuuk, where roughly 500 died before the survivors were repatriated in 1946; the island became a UN trust territory in 1947. Nauru gained full independence on 31 January 1968, becoming a parliamentary democracy under a constitution that remains in force, according to the Government of the Republic of Nauru. Population recovery after the wartime deportations is still marked each 26 October as Angam Day, commemorating the birth in 1932 of the baby whose arrival restored the population to a symbolic threshold of survival, according to the Government of the Republic of Nauru.

Boom, Bust, and a New Name

Phosphate exports peaked in the 1970s and early 1980s at around 2 million tons a year, and Nauru’s offshore trust funds reached roughly US$1 billion at their height, briefly giving citizens one of the highest per-capita incomes in the world, according to the Asian Development Bank. Poor investment decisions, mismanagement, and the near-exhaustion of easily mined phosphate then drove a sharp collapse: exports fell to virtually nothing by 2004, and by mid-2007 combined government and private debt reached an estimated 2,760 percent of GDP. Nauru has since stabilized its finances partly through renewed secondary phosphate mining (resumed in 2005), tuna fishing license revenue, and, controversially, payments from Australia for hosting an offshore Regional Processing Centre for asylum seekers, according to the United Nations in Micronesia. The arrangement has drawn sustained criticism from refugee and human rights advocates over conditions and processing delays, while the Australian and Nauruan governments have defended it as a lawful border-control and development partnership; both positions are widely documented and this article takes no side on the dispute. In 2026, following a parliamentary vote, the government formally notified the UN of the country’s renaming to the Republic of Naoero, restoring an indigenous name for the island, according to the United Nations.

Government and Economy

Nauru is a parliamentary republic. Its unicameral Parliament has 19 elected members, who in turn elect the President from among themselves; the President then forms a Cabinet. Elections are compulsory and held roughly every three years, and the system follows Westminster-style parliamentary traditions established at independence, according to the Government of the Republic of Nauru. There is no officially designated capital; Yaren district functions as the seat of government. The Australian dollar is legal tender. The economy today rests on phosphate mining, fishing license fees, and international development assistance; the Nauru Bureau of Statistics records GDP per capita at roughly AUD 15,000 (2024-2025) and 2021 census population at 11,680, according to the Nauru Bureau of Statistics.

Culture and People

Nauruan society traces descent through 12 traditional matrilineal clans, a structure symbolized by the 12-pointed white star on the national flag, set against a blue field representing the Pacific Ocean and crossed by a gold stripe representing the Equator, according to the Government of the Republic of Nauru. Nauruan is the indigenous language, with English widely spoken in government and business. Most residents live in the narrow coastal belt, where extended family and clan ties remain central to social life, and community events such as Angam Day and district sports competitions remain important markers of national identity.

What Is Nauru Known For?

• Being one of the smallest sovereign states on Earth, with no capital city in the conventional sense.
• A dramatic boom-and-bust history built on phosphate mining, cited widely as a case study in resource dependence.
• A moonscape-like interior of limestone pinnacles left by decades of strip mining.
• Its role in the Parties to the Nauru Agreement (PNA), an eight-nation Pacific coalition, named for the 1982 agreement signed on the island, that manages the world’s largest sustainable tuna purse-seine fishery through a vessel-day licensing system, according to the Parties to the Nauru Agreement.
• Hosting an Australian-funded offshore processing facility for asylum seekers, a long-running and disputed feature of Australia’s border policy.
• Its 2026 renaming to the Republic of Naoero, restoring an indigenous name after more than a century of colonial-era naming.

Why Nauru Matters

Nauru’s significance is out of proportion to its size. Its twentieth-century phosphate wealth and subsequent collapse remain a frequently cited illustration of the risks of resource dependence for small economies. As a Pacific Island state and a founding member of the Nauru Agreement, it has real influence over the management of a global tuna supply chain. And as a small, low-lying nation exposed to drought, coastal erosion, and rising seas along its narrow habitable strip, it has been an active voice in Pacific regional and United Nations forums on climate vulnerability facing small island developing states.
