Pangasinan is strategically situated in the Ilocos Region and occupies the northwestern section of Luzon. Its territory covers a land area of 545,101 hectares, constituting almost one-half (41.89%) of the region’s total land area and 1.6% of the entire Philippine area.
It is bounded in the north by Lingayen Gulf, La Union, and Benguet in the north-east, by Nueva Vizcaya in the east, Nueva Ecija and Tarlac in the south and Zambales and China Sea in the west.
Prominent geographical features are the mountain ranges stretching from Zambales to the western part of the province, as well as the Agno River, also known as the Pangasinan River, that traverses through Pangasinan. The 248-kilometer-long river traces its way from the mountains of the Cordilleras and drains into the Lingayen Gulf. The river and its dams play a vital role in providing power and irrigation to the flatlands of Pangasinan and neighboring provinces.
