The Northern Negros Natural Park is a protected area of the Philippines located in the northern mountainous forest region of the island of Negros in the Visayas. It is spread over five municipalities and six cities in the province of Negros Occidental and is the province's largest watershed and water source for seventeen municipalities and cities including the Bacolod metropolitan area. The park was established first as a forest reserve spanning 107,727 hectares (266,200 acres) on 28 April 1935 through Administrative Act No. 789 signed by Governor-General Frank Murphy. On 7 August 1946, the Northern Negros Forest Reserve was reduced to its present area of 80,454.5 hectares (198,807 acres) with the signing of Proclamation No. 798 by President Manuel Roxas. In 2005, the protected area was converted into a natural park under the National Integrated Protected Areas System (NIPAS) Act by virtue of Proclamation No. 895 signed by President Gloria Arroyo.

The Northern Negros Natural Park is located some 40 kilometres (25 mi) east-northeast of Bacolod, the largest city and capital of Negros Occidental. It covers the highland interior of the island and spans the cities and municipalities of Murcia, Salvador Benedicto, Talisay, Silay, Enrique B. Magalona, Victorias, Cadiz, Sagay, Toboso, Calatrava and San Carlos near the boundary with the province of Negros Oriental. The park is centered on Mount Mandalagan and Mount Silay with their old-growth forests at over 1,000 metres (3,300 ft). Secondary forests are found in the lower slopes which are crossed by four major river systems namely, the Malogo, Imbang, Himoga-an and Bago rivers.
