No. The Pacific Ocean borders the west coast of the United States (California, Oregon, Washington, Alaska, Hawaii).
The Atlantic Ocean borders the east coast (Maine to Florida).
| Coast | Ocean | States |
|---|---|---|
| West | Pacific | CA, OR, WA, AK, HI |
| East | Atlantic | ME, NH, MA, RI, CT, NY, NJ, DE, MD, VA, NC, SC, GA, FL |
| Gulf | Gulf of Mexico (Atlantic marginal sea) | FL, AL, MS, LA, TX |
The confusion may arise from map projections (Pacific centered maps put Americas on the right) or the fact that the Panama Canal connects the two — but geographically, the US west coast is Pacific, east coast is Atlantic.
