US President Donald Trump says he reconsidered renaming the Atlantic Ocean after Google CEO Sundar Pichai warned him against the idea, but the episode has opened a larger question: how far can a president go in changing the names of geographical features that belong to no single country?
Speaking at a rally in South Carolina on October 22, Trump said he had contacted Pichai about renaming the Atlantic Ocean after America or himself. According to Trump’s account, the Google chief executive objected because oceans span multiple countries and urged him not to pursue the proposal.
Trump said he would probably abandon the Atlantic Ocean plan, but then floated another possibility: renaming the Pacific Ocean the “American Ocean”. Google has not independently confirmed the reported conversation, and no formal proposal to rename either ocean has been announced.
The episode follows Trump’s earlier moves to rename the Gulf of Mexico as the Gulf of America and Lake Ontario as Lake America for US federal use. Both changes have demonstrated that a government can alter its own official terminology without securing universal international acceptance.
From Gulf of America to the proposed American Ocean
Trump began his second term in January 2025 by signing an executive order directing the US government to use the name Gulf of America instead of Gulf of Mexico. Federal agencies subsequently updated their geographical databases, and Google Maps introduced the new label for users in the United States.
In August 2026, Trump signed another executive order directing the renaming of Lake Ontario to Lake America for US federal use. Google subsequently reflected the change for users in the United States, while Canadian users continued to see Lake Ontario. Users elsewhere could see both names.
Google says its approach follows official government geographical-name sources. Its mapping policy is therefore not necessarily an endorsement of a president’s personal preference; it is a system for reflecting recognised naming decisions in the relevant jurisdiction.
That distinction is central to the Atlantic Ocean controversy. The US can direct federal agencies to use a different name, but the Atlantic is bordered by numerous countries across North America, South America, Europe and Africa. A US decision would not compel other governments, international organisations, publishers or mapmakers to adopt the same terminology.
The Pacific Ocean presents a similar problem. Although Trump suggested the name “American Ocean”, the Pacific borders countries across Asia, Oceania and the Americas. The proposal would encounter the same question of international recognition even if the US government adopted the new term for its own official purposes.
The difference between renaming a feature for domestic administrative use and establishing a universally accepted geographical name is not merely semantic. It determines what appears on government documents, navigation products, school maps, scientific publications and international reporting.
What presidential power can and cannot change
The US Board on Geographic Names, established in its present form under federal law in 1947, coordinates geographical naming for federal government use. Its responsibilities include standardising names and resolving discrepancies. The board operates through committees dealing with domestic and foreign geographical names.
A president can direct federal agencies to adopt a particular name through executive action, subject to applicable law and the relevant administrative process. The Congressional Research Service has documented how the Trump administration’s executive orders led to official US database changes for the Gulf of Mexico and Lake Ontario.
But those decisions do not automatically bind foreign governments or private companies. Nor do they settle international disputes over the naming of shared geographical features.
The United Nations system for geographical names recognises the practical difficulty of achieving a single agreed name when countries sharing a feature cannot reach consensus. In such cases, the names used by the respective countries may be accepted rather than one country’s preferred terminology overriding the others.
The Gulf of Mexico provides a recent example. The US government uses Gulf of America in its official records, while Mexico continues to use Gulf of Mexico. Google’s presentation varies by location: US users see Gulf of America, Mexican users see Gulf of Mexico, and users in other regions can see both names.
The Associated Press also refused to replace Gulf of Mexico universally with Gulf of America, arguing that the US order did not bind other countries and that its international reporting required recognisable geographical terminology. The dispute led to a legal confrontation after the news agency was restricted from certain presidential press events.
Lake Ontario has illustrated the same limits in relations with Canada. Canadian leaders have rejected the US name change, and Canadian users of Google Maps continue to see the lake’s established name.
An ocean-wide change would be more complicated still. Even if Washington instructed federal agencies to use “American Ocean”, other countries could retain the Atlantic Ocean or Pacific Ocean in their official records. International cartographers and publishers would also have to decide whether to follow the US designation, retain the established name or display both.
Why Google’s role matters
The exchange Trump described with Pichai puts a private technology company at the centre of a dispute over public authority and geographical identity. Google Maps is used internationally, making its naming decisions visible to millions of people and potentially affecting how geographical changes are understood.
Yet Google does not determine international sovereignty or settle disputes between countries. Its own explanation of previous changes says it reflects official government sources and adapts labels according to users’ locations.
That creates a distinction between a map label and an internationally recognised name. A label can change on a screen without changing the geography itself, the territorial rights of neighbouring states or the terminology used by other governments.
It also explains why Google’s response to the Gulf and Lake Ontario changes cannot automatically be taken as a promise to implement every future presidential proposal. The company has said its updates follow established naming sources. The Atlantic proposal has not been confirmed as a formal government decision, and Google has not verified Trump’s account of Pichai’s reported objection.
The wider political significance lies in the ability of a president to influence official language, public-facing technology and the symbolism attached to national identity. Renaming can become a way of projecting national prestige, but its practical reach depends on the jurisdiction and institutions willing or required to adopt the change.
From an ocean to the Strait of Hormuz
Trump’s proposals have extended beyond North American geography. Earlier in October, he raised the possibility of renaming the Strait of Hormuz as the “Trump Strait”, a suggestion made against the backdrop of the strategic waterway’s importance to global energy shipments.
The Strait of Hormuz is a critical route for oil and liquefied natural gas moving from the Persian Gulf towards international markets. A US naming preference would not alter the waterway’s geography, the rights of states in the region or the rules governing maritime navigation.
The same principle applies to the Atlantic and Pacific. Their established names are used in international navigation, scientific research and diplomatic communications. A new US label would not by itself replace that international usage.
Trump has also floated renaming New Mexico as “New America”, but a US state’s name presents a different constitutional and legal question from a name used by federal agencies for a geographical feature. A president cannot simply change a state’s name through an executive order alone; the relevant state-level and constitutional processes would matter.
The sequence of proposals shows why each case needs to be assessed separately. A president may direct federal naming practices in certain circumstances, but the effects depend on the feature involved, the legal authority used and whether other governments recognise the change.
For now, Trump’s account suggests that the Atlantic Ocean proposal has been put aside, while the “American Ocean” idea remains a suggestion rather than an implemented change. The episode leaves a broader lesson: a government can change what its own institutions call a place, but it cannot assume that the rest of the world will follow.
FAQs
- Did Sundar Pichai confirm that he rejected Trump’s Atlantic Ocean proposal?
No. Trump described the conversation publicly, but Google has not independently confirmed the exchange.
- Has the Atlantic Ocean been renamed?
No. There is no confirmed official change to the Atlantic Ocean’s internationally established name.
- Can the US president rename an ocean?
A president can direct federal agencies to use a different name within the scope of US authority and applicable law. Such a decision would not automatically bind other countries or international organisations.
- Why does Google Maps show different names for the Gulf of Mexico?
Google says it follows official geographical-name sources and applies labels according to users’ locations. US users see Gulf of America, while users in Mexico see Gulf of Mexico; users elsewhere may see both names.
- Has Lake Ontario officially become Lake America everywhere?
No. The US government adopted Lake America for federal use, but Canada continues to use Lake Ontario. Google Maps reflects that difference by region.
- Could the Pacific Ocean become the American Ocean?
Trump has floated the idea, but no confirmed official change has been announced. A US designation would not automatically establish a new name internationally.
