Legislative districts of Laguna#2nd District

Laguna initially elected four representatives, at large, to the Malolos Congress in 1898. It was later divided into two representative districts in 1907 for the Philippine Assembly.{{cite PH act|chamber=Act|number=1582|date=January 9, 1907|url=https://lawyerly.ph/laws/view/l5054|title=An Act to Provide for the Holding of Elections in the Philippine Islands, for the Organization of the Philippine Assembly, and for Other Purposes|accessdate=September 4, 2022}}

When seats for the upper house of the Philippine Legislature were elected from territory-based districts between 1916 and 1935, the province formed part of the fourth senatorial district which elected two out of the 24-member senate.

By virtue of Executive Orders No. 84 and 103 issued by Philippine Executive Commission Chairman Jorge Vargas in 1942, the municipality of Infanta (including what is now General Nakar and Real) and the Polillo Islands were transferred to Laguna's jurisdiction, a setup which only lasted for the duration of the Second World War. Two delegates represented the expanded province in the National Assembly of the Japanese-sponsored Second Philippine Republic: one was the provincial governor (an ex officio member), while the other was elected through a provincial assembly of KALIBAPI members during the Japanese occupation of the Philippines. San Pablo, being a chartered city, was represented separately in this short-lived legislative body. Upon the restoration of the Philippine Commonwealth in 1945, the province retained its two pre-war representative districts.

The province was represented in the Interim Batasang Pambansa as part of Region IV-A from 1978 to 1984, and elected four representatives, at large, to the Regular Batasang Pambansa in 1984. Laguna was reapportioned into four congressional districts under the new Constitution{{cite web|title=1987 Constitution of the Philippines - Apportionment Ordinance|url=https://www.officialgazette.gov.ph/constitutions/the-1987-constitution-of-the-republic-of-the-philippines/the-1987-constitution-of-the-republic-of-the-philippines-ordinance/|access-date=June 13, 2016}} which was proclaimed on February 11, 1987, and elected members to the restored House of Representatives starting that same year.
