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.

Aurora, officially the Province of Aurora, is a province in the Philippines located in the eastern part of Central Luzon region, facing the Philippine Sea. Its capital is Baler and borders, clockwise from the south, the provinces of Quezon, Bulacan, Nueva Ecija, Nueva Vizcaya, Quirino, and Isabela.
