Batangas's 1st congressional district

Batangas's 1st congressional district is one of the six congressional districts of the Philippines in the province of Batangas. It has been represented in the House of Representatives of the Philippines since 1916 and earlier in the Philippine Assembly from 1907 to 1916. The district consists of the western Batangas municipalities of Balayan, Calatagan, Lemery, Lian, Nasugbu, Taal and Tuy and the component city of Calaca. It is currently represented in the 19th Congress by Eric Buhain of the Nacionalista Party (NP).

Prior to its second dissolution in 1972, the first district encompassed the western Batangas municipalities of Agoncillo, Balayan, Calaca, Calatagan, Lemery, Lian, Nasugbu, San Luis, San Nicolas, Santa Teresita, Taal, and Tuy. Tanauan was also a part of the district until it was reapportioned to the third district in 1928. Following the restoration of the Congress in 1987, it was reduced to eight municipalities that currently remain within its jurisdiction, while four other municipalities were reapportioned to the second and third districts, respectively.
