Apple Maps has followed Google Maps in renaming the Gulf of America to the Gulf of Mexico.Beyond just renaming it for U.S. users, Apple has seemingly removed all mention of the Gulf of Mexico on Apple Maps,

Microsoft and Apple have not yet addressed whether they will keep the name Gulf of Mexico in their map apps. Google has followed through on a change to its Maps software and apps that now displays Gulf of America on the body of water that's been known as the Gulf of Mexico since the 16th century.
