Renaming Geographic Locations: Process and Implications

On August 27, 2026, President Donald Trump issued an executive order to rename Lake Ontario as “Lake America.” This decision was part of a growing trade conflict with Canada. Ontario Premier Doug Ford initially dismissed the name change as rhetoric but the modification took place regardless.

Previously, President Trump renamed the Gulf of Mexico to the Gulf of America and reinstated Mount McKinley as the name for Denali, Alaska’s highest peak. Such changes often face scrutiny and can appear less critical alongside national challenges. However, the process of renaming locations in the United States is formal and significant.

U.S. Renaming Process

The U.S. Board on Geographic Names, part of the U.S. Geological Survey, standardizes place names. The process involves local initiation; states or counties propose a name change and secure support. Each state handles the procedure uniquely. For example, in 2018, Minnesota renamed a significant lake in Minneapolis to Bde Maka Ska. The Minneapolis Park Board identified it as a Dakota name passed down through oral history. They then secured agreement from county commissioners and the Minnesota Department of Natural Resources before the Board on Geographic Names made it official nationwide.

Changing a name is tedious work, often invoking strong emotions. Consider Denali’s renaming from Mount McKinley, a request proposed by Alaska in 1975. The Board on Geographic Names delayed action due to objections from Ohio delegates, as President McKinley was from Ohio. Eventually, Sally Jewell, appointed by President Obama as Secretary of the Interior, enforced the name change in 2015 by invoking a law allowing for direct action at the federal level if no reasonable progress is made.

Legal Challenges and International Context

Legal challenges can arise when opposing a name change. For instance, the name change of Lake Calhoun to Bde Maka Ska in Minnesota faced court objections. Ultimately, the Minnesota Supreme Court affirmed the name change was legally sound.

Internationally, the process is different. The Gulf of Mexico’s renaming exemplifies such a scenario, as it extends beyond U.S. territory. While the Board on Geographic Names can update U.S. maps to reflect “Gulf of America,” no international body governs naming conventions. Each country decides its geographic names independently, creating potential diplomatic discussions or sanctions to influence name adoption externally.

Mapping companies, including Google, update map names following government changes. Depending on the user’s location, maps can show different names. For example, viewing Google Maps from the U.S. displays “Gulf of America,” while Mexico shows “Gulf of Mexico.” Users can also adjust settings to view maps as though from a different country, illustrating the complex global landscape of geographic naming.
