Maguindanao

Maguindanao (; Maguindanaon: Dairat nu Magindanaw; Iranun: Perobinsia a Magindanao; ) was a province of the Philippines located in the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM). From 2014 to 2023, its provincial capital was Buluan, but the legislative branch of government, the Maguindanao Provincial Board, convened at the old provincial capitol in Sultan Kudarat. It bordered Lanao del Sur to the north, Cotabato to the east, Sultan Kudarat to the south, and Illana Bay to the west.
