Mapanuepe Lake is a freshwater lake located in the municipality of San Marcelino, Zambales in the Philippines. The lake was created after the cataclysmic eruption of Mount Pinatubo in 1991. Lahars following the eruption blocked the drainage of Mapanuepe River, south of the volcano, flooding Mapanuepe Valley together with its settlements. Only the steeple of the church protruding out of the water remained from one of the villages.
