The Mounts Iglit–Baco Natural Park (MIBNP) is a legislated protected area of the Philippines and an ASEAN Heritage Park located in the island of Mindoro in the central Philippines. It was first established in 1970 by virtue of Republic Act No. 6148 as a national park that covered an area of 75,445 hectares surrounding Mount Iglit and Mount Baco in the interior of Mindoro. The park is the home of the largest remaining population of the critically endangered tamaraw. In 2003, the Association of Southeast Asian Nations listed it as one of its four heritage parks in the Philippines. The park has also been nominated to the Tentative List of UNESCO World Heritage Sites in 2006. In 2018, the park was designated as a "Natural Park" under the Republic Act No. 11038 or the Expanded National Integrated Protected Areas Systems (ENIPAS) Act of 2018, which increased the area to 106,656 hectares.
