The North Shore, in the context of geography of the Island of Oahu, refers to the north-facing coastal area of Oahu between Kaena Point and Kahuku Point. The largest settlement is Haleiwa.

The northern hemisphere winter months on the North Shore see a concentration of surfing activity, taking advantage of swells originating in the stormy North Pacific. Notable surfing spots include Banzai Pipeline and Sunset Beach.

The Fox Network TV show North Shore was filmed in the area, as were the last few seasons of Baywatch. ABC's Lost is also filmed on O?ahu. Much of it is filmed on The North Shore although other areas on O?ahu are also used. The North Shore includes the area known as Turtle Bay where the rock formations and constant rolling surf make it ideal as a backdrop for Lost.
