Gulf of California vs. Mexico: A Sea Versus a Nation

The Gulf of California (Sea of Cortez) is a marginal sea of the Pacific Ocean, separating the Baja California Peninsula from the Mexican mainland.

Mexico is a sovereign country bordering the United States, Guatemala, Belize, the Pacific Ocean, the Gulf of Mexico, and the Caribbean Sea.

They are entirely distinct: one is a body of water; the other is a nation. The Gulf of California lies within Mexico’s maritime territory but is not synonymous with the country.
