Naujan Lake is a freshwater lake in the Philippines located in the northeastern corner of the province of Oriental Mindoro on Mindoro Island. The lake is the fifth largest in the country and the main geographical feature of the Naujan Lake National Park. The entire area is a Ramsar Wetland Site since 1999.
The lake is bounded by the towns of Naujan to the north and northeast, Victoria to the west, Socorro to the south and southeast, and Pola to the east. The lake is also bounded by the Naujan Mountains to the north and east of the lake.
Mount Naujan, elevation 1,380 feet (420 m) and one of the inactive volcanoes of the country, is situated northeast of the geographic center of the lake. Several thermal springs and solfataras are reported to exist on the eastern border of the Naujan Lake.
The lakes watershed covers about 30,000 hectares (300 km2). The lake is fed by the Macatoc, Borbocolon, Malayas, Malabo, Maambog, Malbog and Cusay Creek from the east; by Bambang, Tigbao and Tagbakin Creek from the west; and by Subaan and Singulan River from the south. The lake has only one outlet, the Butas River, which flow north then heads east after the Lumangbayan River joins the river and empties to Tablas Strait at Barangay Lumang-bayan, Naujan.
The lake, approximately 8,125 hectares (20,080 acres) in area, is the main feature of the protected area classified as a national park known as the Naujan Lake National Park (NLNP). The lake and adjoining areas totaling 21,655 hectares (53,510 acres) was declared a national park on March 27, 1956 through Proclamation No. 282 by President Ramon Magsaysay.
