Pasay's at-large congressional district is the sole congressional district of the Philippines in the city of Pasay.

[3] Pasay first elected a single representative city-wide at-large for the Regular Batasang Pambansa following the 1984 Philippine constitutional plebiscite that amended the 1973 constitution and abolished the regional at-large assembly districts.

[4] Before 1973, the city was represented in the national legislatures as part of Rizal's 1st and at-large districts and Manila's at-large district.

The district was re-created on February 2, 1987 following the ratification of the 1987 constitution that restored the House of Representatives.

[5] It is currently represented in the 19th Congress by Antonino G. Calixto of the Lakas–CMD.
