Legislative districts of Cotabato

The Legislative Districts of Cotabato, namely the first, second districts and third districts are the representations of the Province of Cotabato in the Philippine House of Representatives.

Cotabato was part of the representation of Mindanao and Sulu from 1916 to 1935, after which it was organized as a lone district.

During the Japanese occupation of the Philippines, the province sent two representatives to the National Assembly of the Second Philippine Republic. Upon the restoration of the Philippine Commonwealth in 1945, the province continued to comprise a lone district. This lone district represented South Cotabato until 1965, and the provinces of Maguindanao and Sultan Kudarat until 1972.

The province became part of the representation of Region XII from 1978 to 1984. It regained its own representations in the Regular Batasang Pambansa in 1984 where it elected 2 assemblymen at-large. Cotabato was divided into two congressional districts under the new Constitution which took effect on February 7, 1987, and each elected its member to the restored House of Representatives starting that same year.
