The Santa Lucia Protected Landscape, also known as the Salcedo Protected Landscape, is a protected area located in the foothills of the Cordillera Central mountain range in the Ilocos Sur province of the Philippines. It protects an important watershed that serves as the water source for the surrounding communities in the municipality of Salcedo. It had an initial area of 174 hectares proclaimed as the Santa Lucia Watershed Forest Reserve in 1938 through Proclamation No. 333 issued by President Manuel Luis Quezon. In 2000, the forest reserve was reestablished as a protected landscape area under the National Integrated Protected Areas System with the signing of Proclamation No. 296 by President Joseph Estrada.
