Legislative district of Shariff Kabunsuan

The Legislative districts of Maguindanao are the representations of the province of Maguindanao in the of the Philippines. The province is currently represented in the lower house of the Congress of the Philippines through its first and second congressional districts.

Cotabato City, an independent component city, only votes as part of the first congressional district of Maguindanao for the purposes of electing congressional representatives.

Prior to gaining separate representation, areas now under the jurisdiction of Maguindanao were represented under the Department of Mindanao and Sulu (1917–1935) and Cotabato (1935–1972).

The enactment of Presidential Decree No. 341 on 22 November 1973 created the Province of Maguindanao out of Cotabato's Maguindanao-majority municipalities. The new province was represented in the Interim Batasang Pambansa as part of Region XII from 1978 to 1984.

Maguindanao (including Cotabato City) first gained separate representation in 1984, when it returned two representatives, elected at large, to the Regular Batasang Pambansa.

Under the new Constitution which was proclaimed on 11 February 1987, the province, including Cotabato City, was reapportioned into two congressional districts; each elected its member to the restored House of Representatives starting that same year.
