Trump Renames Gulf of Mexico to Gulf of America in Executive Order

Jan 20, 2025, 10:54 PM

President Donald Trump has issued an executive order renaming the Gulf of Mexico to the Gulf of America, effective immediately. This decision, part of over 200 executive actions taken on his inauguration day, aims to honor the region's integral role in America's economy and history. The renaming reflects Trump's policy to celebrate American heritage and contributions, as outlined in the order. The Gulf of America, formerly known as the Gulf of Mexico, spans over 1,700 miles of U.S. coastline and is crucial for trade, oil and gas production, fisheries, and tourism. The order mandates the Secretary of the Interior to update the Geographic Names Information System (GNIS) within 30 days to reflect this change.
