Bohol's at-large congressional district
Bohol's at-large congressional district was the provincewide electoral district used to elect members of Philippine national legislatures in Bohol before 1987. Bohol first elected its representatives at-large during the 1943 Philippine legislative election for a seat in the National Assembly of the Second Philippine Republic. Before 1943, the province was represented in the national legislatures through its first, second and third districts. The province was also earlier represented in the Malolos Congress of the First Philippine Republic in 1898 by appointed delegates from Luzon. The three districts were restored in Bohol  ahead of the 1941 Philippine House of Representatives elections whose elected representatives only began to serve following the dissolution of the Second Republic and the restoration of the Philippine Commonwealth in 1945. An at-large district would not be used in the province again until the 1984 Philippine parliamentary election for three seats in the Batasang Pambansa. It became obsolete following the 1987 reapportionment under a new constitution that restored Bohol's three congressional districts.
