The Department of the Interior and Local Government (DILG) assists the President in the exercise of general supervision over local governments. Its mandate is to promote peace and order, ensure public safety, and further strengthen local government capability aimed towards the effective delivery of basic services to the citizenry.

Its attached agencies are the National Police Commission, Philippine National Police, Bureau of Fire Protection, Bureau of Jail Management and Penology, Local Government Academy, and Philippine Public Safety College.

In October 2018, three agencies that were under the Office of the President were transferred to the DILG, namely, the Philippine Commission on Women, National Youth Commission, and the National Commission on Muslim Filipinos. The DILG is at the forefront of priority campaigns against illegal drugs, criminality, corruption, communist terrorism, and violent extremism as it continues to further good governance together with the civil society and other local and international stakeholders.
