Tarlac's at-large congressional district

Tarlac's at-large congressional district is an obsolete electoral district that was used for electing members of Philippine national legislatures in Tarlac before 1987.

Tarlac first elected its representatives at-large during the 1898 Philippine legislative election for three seats in the Malolos Congress, the National Assembly of the First Philippine Republic. Following the installation of U.S. civil government in 1901 and the reorganization of provinces for the Philippine Assembly, Tarlac was divided into a first and second district. The provincewide electoral district was re-created ahead of the 1943 Philippine legislative election for a seat in the National Assembly of the Second Philippine Republic, with an additional seat assigned to its provincial governor. The district became inactive again following the restoration of the House of Representatives in 1945 when Tarlac returned to electing its representatives from its two districts. In the unicameral Batasang Pambansa that replaced the House in 1978, Tarlac was included in the multi-member regional electoral district of Region III (Central Luzon) for its interim parliament. The district was again utilized in the 1984 Philippine parliamentary election when Tarlac was granted two seats in the regular parliament.

After 1986, Tarlac elected its representatives from three single-member congressional districts drawn under a new constitution.
