The Mati Protected Landscape is a protected area located in Davao Oriental on the southern Philippine island of Mindanao. It protects the watershed in Mati which is the source of water supply for the city's Mati Waterworks System. The protected area was established in 1967 when 890 hectares (2,200 acres) of forest in Central Mati was proclaimed as the Mati Watershed Forest Reserve through Proclamation No. 222 issued by President Ferdinand Marcos.
