# Legislative districts of Maguindanao

The legislative districts of Maguindanao were the representations of the province of Maguindanao and the independent component city of Cotabato in the various national legislatures of the Philippines. The province and the city were represented in the lower house of the Congress of the Philippines through their first and second congressional districts from 1987–2022.

## History

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 November 22, 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 February 11, 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.
The province of Shariff Kabunsuan, established with the passage of Muslim Mindanao Autonomy Act No. 201 and its subsequent approval by plebiscite, was created out of Maguindanao's western municipalities in 2006. Per Section 5 of MMA Act No. 201, Cotabato City was grouped with Shariff Kabunsuan for the purpose of electing a congressional representative. It was this specific provision that became the subject of the Supreme Court case that ultimately voided MMA Act No. 201 for being unconstitutional, and leading to the disestablishment of the Shariff Kabunsuan in 2008 and the return of its territory to Maguindanao. In the brief period of Shariff Kabunsuan's existence the First District of Maguindanao—Cotabato City was known as the Lone District of Shariff Kabunsuan—Cotabato City, while the Second District was known as the Lone District of Maguindanao.
The districts were dissolved in 2022 following the division of Maguindanao and replaced by Maguindanao del Norte's at-large congressional district and Maguindanao del Sur's at-large congressional district
