Zambales is a province in the Philippines located in the Central Luzon region in the island of Luzon. Its capital is the Municipality of Iba which is strategically located in the middle of the province. Zambales borders Pangasinan to the north and northeast, Tarlac to the east, Pampanga to the southeast, Bataan to the south and the West Philippine Sea to the west. With a total land area of 3,830.83 square kilometres (1,479.09 sq mi) (including the independent city of Olongapo), Zambales is the second largest among the seven provinces of Central Luzon after Nueva Ecija. The province is noted for its mangoes, which are abundant from January to April.

Zambales does not have a functional airport – the closest functional airport is the Clark International Airport in the neighbouring province of Pampanga. Subic Bay International Airport, which is located in Cubi Point (geographically located inside Morong, Bataan) in the Subic Bay Freeport Zone is no longer functional for domestic and international flights.

The Freeport Zone (SBFZ) is host to many tourist attractions which include casinos, parks, malls, beach-side huts, cottages and resorts, as well as historical sites.
