Pacific coast may be used to reference any coastline that borders the Pacific Ocean. Geography Americas North America Countries on the western side of North America have a Pacific coast as their western or south-western border. One of the notable exceptions is Panama, where the Pacific coast is primarily on its southern border.

The unique position of Panama in relation to the Pacific Ocean resulted in the ocean initially being named the South Sea.
