Bataan, officially the Province of Bataan, is a province in the Central Luzon region of the Philippines. Its capital is the city of Balanga while Mariveles is the largest town in the province. Occupying the entire Bataan Peninsula on Luzon, Bataan is bordered by the provinces of Zambales and Pampanga to the north. The peninsula faces the South China Sea to the west and Subic Bay to the north-west, and encloses Manila Bay to the east.

Central Luzon, designated as Region III, is an administrative region in the Philippines, primarily serving to organize the 7 provinces of the vast central plains of the island of Luzon, for administrative convenience. The region contains the largest plain in the country and produces most of the country's rice supply, earning itself the nickname "Rice Granary of the Philippines". Its provinces are: Aurora, Bataan, Bulacan, Nueva Ecija, Pampanga, Tarlac and Zambales. Pangasinan was formerly a province of Central Luzon before President Marcos signed Presidential Decree No. 1, 1972, incorporating it into Ilocos Region. Additionally, the province of Aurora was part of the defunct political region Southern Tagalog when the region was divided into Calabarzon and Mimaropa, upon the issuance of Executive Order No. 103, dated May 17, 2002, by then-President Gloria Macapagal Arroyo, which transferred Aurora to Central Luzon.
