Bataan is a province situated in the Central Luzon region of the Philippines. Its capital is the City of Balanga. 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.

The Battle of Bataan is famous in history as one of the last stands of American and Filipino soldiers before they were overwhelmed by the Japanese forces in World War II. The Bataan Death March was named after the province, where the infamous march started.
