Thelegislative districts of Iloilo are the representations of theprovince ofIloilo in thevarious national legislatures of thePhilippines. The province is currently represented in thelower house of theCongress of the Philippines through itsfirst,second,third,fourth andfifth congressional districts.

Thehighly urbanized city ofIloilo City and the province ofGuimaras were last represented as part of Iloilo in 1986 and 1995, respectively.

Iloilo was divided into five representative districts in 1907. Minor adjustments were made to the composition of thethird,fourth, andfifth districts through Act No. 3036 enacted on March 9, 1922. When seats for theupper house of thePhilippine Legislature were elected from territory-based districts between 1916 and 1935, the province formed part of theseventh senatorial district which elected two out of the 24-member senate.

In the disruption caused by theSecond World War,two delegates represented the province in theNational Assembly of the Japanese-sponsoredSecond Philippine Republic: one was the provincial governor (anex officio member), while the other was elected through a provincial assembly ofKALIBAPI members during theJapanese occupation of the Philippines.Iloilo City, being a chartered city, wasrepresented separately in this short-lived legislative body. Upon the restoration of thePhilippine Commonwealth in 1945, the province retained its five pre-war representative districts.

The province was represented in theInterim Batasang Pambansa as part ofRegion VI from 1978 to 1984. In1984 the province electedfive representatives, at large, to theRegular Batasang Pambansa.

The province, excluding thehighly urbanized ofcity of Iloilo, was reapportioned into fivecongressional districts under the new Constitution^[1] which was proclaimed on February 11, 1987. The five districts elected members to the restored House of Representatives startingthat same year.Iloilo City also elected itsown representative in the 1987 election.

On May 22, 1992 the Provincial Board of Canvassers of Iloilo affirmed the results of the May 11, 1992 plebiscite on the proposed establishment of Guimaras (a sub-province of Iloilo since 1966) as a regular province by virtue of Section 462 of Republic Act No. 7160 (Local Government Code of 1991).^[2] Guimaras continued to be represented as part of thesecond district of Iloilo until it elected itsown representative in the1995 elections.
