Norzagaray

Norzagaray, officially the Municipality of Norzagaray (Tagalog: Bayan ng Norzagaray), is a municipality in the province of Bulacan, Philippines. According to the 2024 census, it has a population of 140,697 people.

It is the location of Angat Dam which sits on the lower realms of the Sierra Madre Mountain range. It is notable for being a major water and power supply for the National Capital Region.

The nucleus of what today is the town of Norzagaray traces from the old barrio Casay and barrio Matictic which was ecclesiastically and politically administered by the Augustinians from the town of Angat as its visitas as shown in the document "Mapa del Teritorio de Bulacan" by Fray Emmanuel Blanco, O.S.A. in 1832 which appeared in another document "Administracion Espiritual de los Padres Agustinos calzados de la Provincia del Dulce Nombre de Jesus de las Islas Filipinas" of Fray Francisco Villacorta in 1833.

The people of Barrio Casay worked for reforms politically, socially and economically, in order to be separated from Angat. They succeeded in their separation bid through Governor-General Fernándo Norzagaray y Escudero, who issued a Real Cedula declaring barrio Casay together with barrio Matictic to be constituted as a new independent town from Angat. Political boundaries of Angat and Pueblo de Casay y Matictic were demarcated and the newly created town was renamed as "Norzagaray" in honor of the Governor-General.

During the American occupation of the Philippines, Norzagaray was reunited with Angat by virtue of Act No. 932 beginning in 1903.

On September 13, 1977, Barangays Bayabas and Kabayunan were ceded to the newly established municipality of Doña Remedios Trinidad, by virtue of Presidential Decree No. 1196.

The town of Norzagaray is bordered by San Jose del Monte, and Rodriguez, to the south; by General Nakar to the east; Santa Maria to the west; Angat to the north-west; and Doña Remedios Trinidad to the north. Norzagaray is 48 kilometres (30 mi) from Malolos, 47 kilometres (29 mi) from Manila, 17 kilometres (11 mi) from San Jose del Monte, and 4 kilometres (2.5 mi) from Angat.

Norzagaray was previously part of the 3rd district of Bulacan from 1987 to 2022, when it was moved to the newly created 6th district along with Angat and Santa Maria.
