San Jose del Monte, officially the City of San Jose del Monte (abbreviated as SJDM or CSJDM); Tagalog: Lungsod ng San José del Monte; Southern Alta: Siyudad na San José del Monte; Spanish: Ciudad de San José del Monte; Spanish pronunciation: [ˌsaŋ xoˌse ðel ˈmonte]; Tagalog pronunciation: [ˌsɐn hoˌsɛ dɛl ˈmonte]), is a component city in the province of Bulacan, Philippines. According to the 2024 census, it has a population of 685,688 people, making it the largest local government unit within the province of Bulacan and Central Luzon, and the 18th most populated city in the Philippines.

It was proclaimed as a component city on 10 September 2000, through Republic Act No. 8797. Its conversion into a highly urbanized city was by virtue of Proclamation No. 1057 issued by President Rodrigo Duterte on 4 December 2020; the conversion was rejected on a referendum held on 30 October 2023, by the voters of Bulacan including the concerned city.

San José del Monte derived its name from Saint Joseph, whose statue was found in a veritable forest. The hunters called it as such, which means “Saint Joseph of the Mountain” in Spanish.

Early accounts of the founding of the city, as gathered from the old people, contend that it was formerly a part of the town of Meycauayan. This is supported by a decree from the Archbishop of Manila dated March 1750 on the creation of new municipalities. The municipality of San Jose del Monte was then officially founded on 2 March 1752.

The decree included the list of families who volunteered to be relocated. These families, most if not all from Lagulo (now Malhacan) in Meycauayan, brought with them rice, wine, nganga, and salt in exchange for the wild pigs, deer, yantok, and almasigan of the Itas and Dumagats, the native inhabitants of the area. Solares, including intended lots for main roads, were peacefully distributed to the new occupants after being measured and surveyed.

In all probability, the hunters reported their findings to the parish priest of Meycauayan. It was said that the priest built a stone church at the site where the town proper is now located. The statue was installed in the new church. Extant Catholic Church records reveal that the first parish priest was Father Antonio de Moral. He took charge of the parish in 1845.

During the revolt against Spain, the town became a battleground between the Katipuneros and the Spanish forces. The revolutionaries lost and the vengeful Spanish soldiers burned down the settlement. The townspeople fled for their lives to nearby towns. At the advent of American rule, it was made a part of Santa Maria until 1918 when the town was recreated and Ciriaco Gallardo appointed the first municipal president. Public schools were opened at the start of the American regime but due to the scarcity of the population, the highest grade organized was at the fourth grade.

During the Japanese occupation, the town became an ideal hiding place for the locally recognized guerrillas because of the town's hilly and wooden terrain. The Japanese Imperial Army took over the local government of San Jose del Monte from 1942 to 1943. In resistance, the municipality formed its guerrilla unit. San Jose del Monte experienced large casualties when the Americans bombed the town center on 11 January 1945, and again on 14 January 1945. When the combined Filipino and American troops came, peace reigned but not for long.
