Donald Trump has once again placed geographic names at the center of the U.S. political debate. The U.S. president has proposed renaming New Mexico “New America” and posted on social media an image of the state’s outline in which the word “Mexico” is crossed out and replaced with “America.”
The post was later shared by the White House on its X account, although it has not so far led to a formal process to change the state’s name. Reuters reported that Trump presented the designation as an idea from his supporters and described it as “prestigious” and “beautiful.”
The proposal comes days after the president signed an executive order on August 27 directing the U.S. federal government to refer to Lake Ontario, which is shared by the United States and Canada, as “Lake America.” The White House officially lists the order among the presidential actions of August 2026.
A new episode in the renaming policy
This is not the first time Trump has pushed for changes of this kind. At the start of his second term, he ordered U.S. federal agencies to use the name “Gulf of America” to refer to the Gulf of Mexico. He has also restored the name Mount McKinley for Denali in Alaska and, more recently, suggested naming the Strait of Hormuz the “Trump Strait.”
The New Mexico initiative, however, presents a fundamental difference. The president can order changes to the terminology used by certain federal agencies for geographic features, but he does not have constitutional authority to unilaterally change the name of one of the states that make up the United States. Any potential change would have to originate with the state itself, meaning that Trump’s proposal is, for now, essentially political and symbolic.
New Mexico Governor Michelle Lujan Grisham, a Democrat, has rejected the possibility. Her response also underscored the deep historical roots of a name that predates the very existence of the United States as a country. The name New Mexico dates back to the period of Spanish presence in North America, long before the territory joined the United States in the 19th century.
A name with centuries of history
The issue has a particularly significant historical dimension. New Mexico was not named because of its later proximity to independent Mexico. The designation dates from the Spanish colonial era and was in use centuries before the creation of the modern United States and Mexico.
The territory later remained under Mexican sovereignty following Mexico’s independence and became part of the United States after the war between the two countries and the 1848 Treaty of Guadalupe Hidalgo. New Mexico ultimately became the Union’s 47th state in 1912. That history explains the significant presence of Hispanic and Mexican heritage in its cultural and social identity.
The presidential proposal therefore carries implications that go beyond a simple cartographic change. The name New Mexico is part of a history tied successively to Indigenous cultures, the Spanish presence, Mexico, and the United States, and is among the most visible reminders of the complex historical formation of the U.S. Southwest.
For now, no legal process is underway to replace it. What the initiative does confirm is the continuation of a practice Trump has used at different points during his second term: employing geographic names as tools of national identity and political communication. The New Mexico case, however, has a limitation that did not exist in some previous episodes: any effective change would depend on the state itself, rather than solely on a White House decision.
