Parliamentary districts of Bangsamoro refers to the electoral districts or constituencies into which the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) of the Philippines is divided for the purpose of electing 32 of the 80 members of the Bangsamoro Parliament.
The districts were initially created on February 28, 2024, and were subsequently reapportioned under Bangsamoro Autonomy Act No. 86 in January 2026. The 32 districts elected their first representatives in the 2026 Bangsamoro Parliament election on September 14, 2026.
Background The Bangsamoro Organic Law mandates the establishment of the a legislature for the Bangsamoro autonomous region. Thirty-two out of 80 members of the Bangsamoro Parliament are to come from parliamentary districts, which is distinct from the legislative districts of the national Philippine Congress.
The first attempt to establish parliamentary districts was through Parliament Bill No. 6.
Parliament Bill No. 297 was filed on December 18, 2023, during the second Bangsamoro Transition Authority Parliament.
The first public consultations on the bill started on January 15, 2024. There was debates on how the districts should be allocated. This includes advocacy for more districts for some localities than what is proposed on the bill.
On February 28, 2024, the Bangsamoro Parliament approved the bill proposing the creation of the parliamentary districts which became Bangsamoro Act No. 58. The bill was signed by Chief Minister Murad Ebrahim.
The exclusion of Sulu from the Bangsamoro due to a Supreme Court decision meant that the province will not be part of the inaugural 2025 regional elections. If the seven Sulu districts are not reallocated in time for the 2025 elections, the Sulu seats could remain unfilled. Parliament Bill No. 351 was filed to redistribute the seats. An additional district is proposed for each of the remaining five provinces, Cotabato City and the Special Geographic Area. Muslimin Sema, speaking as chairman of the Moro National Liberation Front opposes the reallocation insisting that the national Congress could work on Sulu's reintegration to the autonomous region. The Parliament failed to reallocate the seven parliamentary districts on time, rendering only 25 seats to be contested for the elections out of the allotted 32.
Parliament Bill No. 351 was approved nevertheless on August 19, 2025. The bill which became Bangsamoro Autonomy Act No. 77 was signed by Chief Minister Abdulraof Macacua on August 28, 2025.
Both Acts No. 58 and 77 were declared unconstitutional by the Supreme Court which also ordered the parliament to make a new law determining the districts by October 31, 2025.
The replacement law, Parliament Bill 415 was passed on January 13, 2026. Macacua signed the bill into law on January 20, 2026, becoming Bangsamoro Autonomy Act No. 86.
