Legislative districts of Bulacan

The Legislative Districts of Bulacan, namely the first, second, third and fourth districts, are the current representations of the province of Bulacan in the Philippine House of Representatives.

The province was divided into two representative districts until 1972. Upon its inclusion into the newly organized Metropolitan Manila Area on November 7, 1975 by virtue of Presidential Decree No. 824, the municipality of Valenzuela was separated from Bulacan and ceased to be part of the province's representation, beginning 1978.

Bulacan was represented in the Interim Batasang Pambansa as part of Region III from 1978 to 1984, and elected four representatives at-large to the Regular Batasang Pambansa in 1984. Effective February 11, 1987, the province was redistricted into four congressional districts under the new Constitution, and elected members to the restored House of Representatives starting that same year.
