Nine U.S. States Bordering the Atlantic Ocean

The nine states with Atlantic coastline (north to south):

1. Maine
2. New Hampshire
3. Massachusetts
4. Rhode Island
5. Connecticut
6. New York
7. New Jersey
8. Delaware
9. Maryland

(Virginia, North Carolina, South Carolina, Georgia, and Florida also border the Atlantic but are often grouped as "South Atlantic" or "Southeast." The question likely refers to the traditional "Northeast/Mid‑Atlantic" nine.)
