Mount Makiling, or Mount Maquiling, is an inactive stratovolcano located in the provinces of Laguna and Batangas on the island of Luzon, Philippines. The mountain rises to an elevation of 1,090 m above mean sea level and is the highest feature of the Laguna Volcanic Field. The volcano has no recorded historic eruption but volcanism is still evident through geothermal features like mud spring and hot springs. South of the mountain is the Makiling-Banahaw Geothermal Plant. The Philippine Institute of Volcanology and Seismology classifies the volcano as "Inactive".
Mount Makiling is a state-owned forest reserve administered by the University of the Philippines Los Baños. Prior to its transfer to the university, the mountain was the first national park of the Philippines. Mount Makiling National Park was established on February 23, 1933 by Proclamation No. 552. However, it was decommissioned as a national park on June 20, 1963 by Republic Act no. 3523 when it was transferred to the University for use in forestry education and information.
The mountain is sacred to many pilgrims and is widely believed to be the home of an anito named Maria Makiling.
