Does the United States Have Oceans Within Its Borders? No, But It Borders Three

There are no oceans located entirely within the United States. Instead, the country is bordered by three major marine bodies:

• Atlantic Ocean on the East Coast
• Pacific Ocean on the West Coast
• Gulf of Mexico on the Southeast Coast (a marginal sea of the Atlantic)

Additionally, the U.S. has coastline on the Arctic Ocean (Alaska) and the Bering Sea, but the three above are the primary oceanic borders.
