Zamboanga City's at-large congressional district is an obsolete congressional district that encompassed the entire Zamboanga City prior to its 2004 reapportionment that took effect in 2007.[1] It existed from 1984 to 2007, when Zamboanga elected a representative city-wide at-large to the Batasang Pambansa and to the restored House of Representatives.[2] Before 1984 when it was granted its own seat in the regular Batasan assembly as a highly-urbanized city, Zamboanga was represented as part of the multi-member Region IX's at-large assembly district for the Interim Batasang Pambansa and was also earlier included in Zamboanga del Sur's at-large congressional district for the Third Philippine Republic congresses. It was last represented by Erico Basilio Fabian of the Laban ng Demokratikong Pilipino (LDP).[2]
