The Maulawin Spring Protected Landscape is a protected landscape area of forested hills and several rivers and streams located in the province of Quezon on southern Luzon island in the Philippines. It was originally created in 1939 to protect the watershed in the municipality of Guinayangan known as the Maulawin Spring Watershed Forest Reserve declared through Proclamation No. 365 by President Manuel Luis Quezon. It had an initial area of 60 hectares. In 2000, the forest reserve was enlarged and was redesignated as a protected landscape under the National Integrated Protected Areas System by virtue of Proclamation No. 295 issued by President Joseph Estrada. It is the only source of potable water for domestic consumption of the more than 40,000 residents of Guinayangan.
