The National Park of American Samoa is a national park in the United States territory of American Samoa, distributed across four islands: Tutuila, Ofu, Olosega, and Ta‘ū. The park preserves and protects coral reefs, tropical rainforests, fruit bats, and the Samoan culture. Popular activities include hiking and snorkeling. Of the park's , is coral reefs and ocean. The park is the only American National Park Service system unit south of the equator. Delegate Fofó Iosefa Fiti Sunia introduced a bill in 1984, at the request from Bat Preservers Association and Dr. Paul Cox, to include American Samoa in the Federal Fish and Wildlife Restoration Act. The purpose of the bill was to protect the habitat for the Flying fox as well as to protect the old rainforest. The bill marked the beginning of American Samoa's entry into the U.S. National Park System. The National Park Service began the work of establishing the national park in July 1987. The National Park of American Samoa was established on October 31, 1988, by Public Law 100-571 but the NPS could not buy the land because of traditional communal land system. This was resolved on September 10, 1993, when the National Park Service entered into a 50-year lease for the park land from the Samoan village councils. In 2002, Congress approved a thirty percent expansion on Olosega and Ofu islands. In September 2009 an earthquake and tsunami produced several large waves, resulting in 34 confirmed deaths, more than a hundred injuries and the destruction of about 200 homes and businesses. The park encountered major damage. The visitor center and main office were destroyed but there was only one reported injury among the NPS staff and volunteers. The Tutuila unit of the park is on the north end of the island near Pago Pago. It is separated by Mount Alava () and the Maugaloa Ridge and includes the Amalau Valley, Craggy Point, Tāfeu Cove, and the islands of Pola and Manofā. It is the only part of the park accessible by car and attracts the vast majority of visitors to the area.
