The Pacific Historic Parks (PHP) is a non-profit organization dedicated to financially supporting National Park Service (NPS) educational and interpretive initiatives throughout the Pacific region. Kalaupapa National Historical Park on the island of Molokai, the USS Arizona Memorial at Pearl Harbor, Hawaii, War in the Pacific National Historical Park on Guam, and American Memorial Park on Saipan all receive significant aid from PHP to communicate the ideas of courage and sacrifice that these sites represent.

Chief among PHP's revenue resources are its bookstores. Through the sale of books, posters, dvds and other products pertaining to WWII in the Pacific, PHP generates income which it can then allocate to crucial interpretive projects and as direct aid to the National Park Service.
