Batangas City (Filipino: Lungsod ng Batangas) is a first class component city and capital of the Province of Batangas, Philippines. It is the largest city in the province in terms of land area, and is currently classified as one of the fastest urbanizing cities of the Philippines. According to the 2015 census, the city has a population of 329,874 people.

Known as the "Industrial Port City of Calabarzon," Batangas City is home to the Batangas International Port, one of the busiest passenger and container terminals in the Philippines, as well as host to one of the largest oil refineries in the country, three natural gas power plants, and several other major industries. In addition, the city also serves as a commercial, educational, health services, tourism, and transportation center in the region.

The first Spanish missionaries arrived in Batangas City since 1572 due to group migration. Finally, in 1581, Spanish authorities governing the Philippines created a pueblo in the area which included the hill (now Hilltop) where the present Provincial Capitol of Batangas stands after the formal end of the Coumintang Kingdom. The town was named "Batangan" because huge logs, locally called "batang", abounded in the place. The Spanish government appointed Don Agustin Casilao as Batangan's first gobernadorcillo. Said title of "little governor" as head of the pueblo or municipio was replaced in 1894 by "capital municipal." It is not clear who succeeded Casilao nor is it known whether there were subsequent appointments of capital municipal. Don Agustin Casilao is sometimes referred to as Agustino or Augustino in some sources. By 1870, its barangays were Balagtas, Bilogo, Bolbok, Bukal, Catandala, Konde, De La Paz, Kumintang Ibaba, Matuko, Mapagong, Paharang Kanluran, Pairang, Pinamucan, Patulo, Sampaga, San Agapito, San Isidro and Talahib.

At the coming of the Americans in the early 1900s, local civil government of Batangas was set up. It took effect on July 4, 1901 with Jose Villanueva elected as "Municipal President." His term expired in 1903.
