Salcedo is a municipality located in the province of Ilocos Sur, in the Ilocos Region (Region I) of the Philippines. It is situated along the northern coast of the island of Luzon, bordered by the South China Sea to the west and other municipalities within Ilocos Sur to the east. According to the Philippine Statistics Authority, Salcedo has a population of approximately 9,000 as of the 2020 census. The municipality is classified as a fourth-class municipality in terms of income.
Administratively, Salcedo is divided into 12 barangays, each consisting of puroks and sitios. As with other local government units in the Philippines, it operates under the Local Government Code, with a mayor serving as the local chief executive and a municipal council acting as the legislative body.
The economy of Salcedo is primarily agricultural, with rice, corn, and vegetables being key crops. Fishing also contributes to the local economy due to the municipality’s coastal location. Infrastructure includes basic public services such as elementary and secondary schools, a municipal hall, and health centers.
The annual festival, Binacay Festival, is celebrated in honor of the town's patron saint, San Juan Bautista (St. John the Baptist), reflecting the area’s strong Roman Catholic traditions. The name "Binacay" is derived from a local term associated with the early settlement history of the area.
Salcedo is accessible via the Ilocos Sur Coastal Road, part of the larger Philippine highway network. Public transportation includes jeepneys and tricycles serving local routes.
Historically, the region was influenced by Spanish colonial administration, and like many municipalities in Ilocos Sur, it exhibits remnants of Spanish-era cultural and religious practices. Accurate information on pre-colonial history or early settlement details specific to Salcedo is limited in available sources.
