Oceans Bordering North America: Atlantic, Pacific, Arctic

North America is bounded by three oceans:

• Atlantic Ocean – east coast (from Labrador to Florida/Gulf of Mexico).
• Pacific Ocean – west coast (Alaska to Baja California).
• Arctic Ocean – north coast (Alaska, Canadian Arctic Archipelago, Greenland).

The Gulf of Mexico and Caribbean Sea are marginal seas of the Atlantic; Hudson Bay connects to the Arctic.
