Zambales is a province of the Philippines located in the Central Luzon region in the island of Luzon. Its capital is Iba. Zambales borders Pangasinan to the north, Tarlac and Pampanga to the east, Bataan to the south and the West Philippine Sea to the west. With a land area of 3,830.83 km2, Zambales is the second largest among the seven provinces of Central Luzon. The province is noted for its mangoes, which are abundant from January to April.
The province's name came from the word zambal, which is a Hispanized term for Sambali. Zambal refers to the language spoken by the early Austronesian inhabitants of the place. A contending version states that the name was derived from the word samba, meaning worship, because the Spanish supposedly found the native inhabitants to be highly superstitious; worshiping the spirits of their ancestors.
The area now occupied by Zambales was first explored by the Spanish in 1572, led by Juan de Salcedo. Among the earliest towns founded were Subic (1572), Botolan (1572), Masinloc (1607), Iba (1611), and Santa Cruz (1612). Masinloc became the province's first capital. However, the capital was moved among the last three towns above during its history before settling in Iba, due to its strategic location. Seven of the province's original northern towns, which included Bolinao, Infanta and Alaminos were later transferred under the jurisdiction of Pangasinan because of their distance from the capital.
