The Pantabangan–Carranglan Watershed Forest Reserve is a conservation area located in the upper reaches of the Pampanga River in Nueva Ecija, Philippines, and borders the Sierra Madre and Caraballo Mountains in Aurora and Nueva Vizcaya. It encompasses 84,500 hectares (209,000 acres) of the drainage basin surrounding the Pantabangan Lake, an impoundment of the Pampanga River by the Pantabangan Dam. The multi-purpose dam is situated at the confluence of Pampanga River's two headwaters, namely the Pantabangan and Carranglan Rivers in the municipality of Pantabangan. It stretches above the dam site for 21 kilometres (13 mi) to where Carranglan River originates in the Caraballo on the north, and for 18 kilometres (11 mi) to where Pantabangan River originates in the Sierra Madre on the east. It is considered a critical watershed for the agricultural economy and hydroelectric power generation in the region of Central Luzon.

Proclamation No. 561 was signed by then–President Ferdinand Marcos on May 21, 1969, establishing the reserve's boundaries and protecting the area for watershed purposes. Its management was handed over to the Bureau of Forestry of the DENR, the Reforestation Administration, the National Waterworks and Sewerage Authority (NAWASA, now the MWSS), the National Irrigation Administration (NIA), Bureau of Public Works (now DPWH), Bureau of Public Soils (now Bureau of Soils and Water Management), and the National Power Corporation. A month later, President Marcos authorized the construction of the Upper Pampanga River Project at the reserve with the Pantabangan Dam as its centerpiece. Construction started in March 1971 with residents at the dam site relocated to the upper portion of Pantabangan by the Department of Agrarian Reform and NIA. By the time the Pantabangan Dam was completed in August 1974, eight barrios have been submerged by its reservoir, namely the old Pantabangan poblacion, Conversión, Villarica, San Juan, Cadaclan, Napon-Napon, Liberty and Marikit.
