The legislative district of Pateros–Taguig is the combined representation of the independent municipality of Pateros and eastern part of the highly urbanized city of Taguig in the Congress of the Philippines.
During World War II, both towns were represented as part of the at-large district of Rizal in the National Assembly of the Second Philippine Republic from 1943 to 1944.
Taguig and Pateros were grouped with Muntinlupa to form a single parliamentary district which returned one representative to the Regular Batasang Pambansa in 1984.
Taguig and Pateros formed one congressional district under the new Constitution[2] proclaimed on February 11, 1987; it elected its member to the restored House of Representatives starting that same year.
Despite being enacted by Congress on February 11, 1998, the said law only took effect on December 8, 2004, after the Commission on Elections issued a resolution confirming that the affirmative votes for cityhood prevailed in the ballot recount.
