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.
