The Bangsamoro Organic Law, also known as the Bangsamoro Basic Law (BBL), and officially designated as Republic Act No. 11054, is a Philippine law that provided for the establishment of the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM).

The Moro Islamic Liberation Front is an Islamist group based in Mindanao seeking an autonomous region of the Moro people from the central government. The group has a presence in the Bangsamoro region of Mindanao, the Sulu Archipelago, Palawan, Basilan, and other neighbouring islands. The armed wing of the group was the Bangsamoro Islamic Armed Forces (BIAF), although the name of its parent organization, the MILF, was often used to refer to the BIAF. In July, 2018, the Philippine government passed the Bangsamoro Organic Law, giving more autonomy to Muslims. In return, MILF announced that it would disarm its 30,000 fighters.
