Legislative district of Olongapo

The Parliamentary District of Olongapo City was the representation of the city of Olongapo in the Regular Batasang Pambansa from 1984 to 1986.

From 1907 to 1972 Olongapo was represented as part of the lone district of Zambales. Olongapo was granted its separate representation in the Regular Batasan after it was declared a highly urbanized city on December 7, 1983. The city was re-grouped with Zambales for representation in the restored House of Representatives and became part of the province's first congressional district under the new Constitution which took effect on February 7, 1987.
