This is a list of protected areas of the Philippines administered by the Department of Environment and Natural Resources' Biodiversity Management Bureau under the National Integrated Protected Areas System (NIPAS) Act of 1992. As of 2012, there are 240 protected areas in the Philippines covering a total area of 35,700 square kilometres (13,800 sq mi) – 11.9% of the Philippines' total land area.
The first important legislation that formed the basis of the current system of national parks and protected areas in the Philippines is the Philippine Commission Act No. 648 enacted in 1903 by the US Congress. This act authorized the Civil Governor to "reserve for civil public purposes, and from sale or settlement, any part of the public domain not appropriated by law for special public purposes."
A total of eight national reserves had been established on July 26, 1904 pursuant to this law. These are: Lamao Forest Reserve in Bataan, Mariquina Reserve in Rizal, Angat River Reserve in Bulacan, Caliraya Falls Reserve in Laguna, La Carlota Reserve in Negros Occidental, San Ramon Reserve in Zamboanga, Magalang Reserve in Pampanga, and Hacienda San Antonio in Isabela. In the same year, the Forest Act of 1904 (Act No. 1148) was adopted that expanded the scope of protected areas in the Philippines. Among the first of such mountain forest reserves to be declared was Mount Maquiling declared on November 21, 1910.
