the Philippines

In the Philippines, regions (Filipino: rehiyon, ISO 3166-2:PH) are administrative divisions that serve primarily to organize the provinces (lalawigan) of the country for administrative convenience. Currently, the archipelagic republic of the Philippines is divided into 18 regions (17 administrative and 1 autonomous). Most government offices are established by region instead of individual provincial offices, usually (but not always) in the city designated as the regional center.

The regions themselves do not possess a separate local government, with the exception of the Autonomous Region in Muslim Mindanao, which has an elected regional assembly and governor. The Cordillera Administrative Region was originally intended to be autonomous (Cordillera Autonomous Region), but the failure of two plebiscites for its establishment reduced it to a regular administrative region.


Regions first came to existence in on September 24, 1972, when the provinces of the Philippines were organized into 11 regions by Presidential Decree № 1 as part of the Integrated Reorganization Plan of President Ferdinand Marcos.

Since that time, other regions have been created and some provinces have been transferred from one region to another.

  • July 7, 1975: Region XII created and minor reorganization of some Mindanao regions.[1]
  • July 25, 1975: Regions IX and XII declared as Autonomous Regions in Western and Central Mindanao respectively.[2]
  • August 21, 1975: Region IX divided into Sub-Region IX-A and Sub-Region IX-B. Minor reorganization of some Mindanao regions.[3]

  • October 12, 1990: Executive Order 429 issued by President Corazon Aquino to reorganize the Mindanao regions but the reorganization never happened (possibly due to lack of government funds).[9]
  • February 23, 1995: Region XIII (Caraga) created and minor reorganization of some Mindanao regions. Sultan Kudarat transferred to Region XI.[10]

List of regions[edit]

Administrative regions[edit]

Map of the Philippine regions before the establishment of the Negros Island Region

As of May 2015, the Philippines consists of 18 administrative regions, with one being autonomous. Some of the region designations include numeric components, some do not.[19] These regions are geographically combined into the three island groups of Luzon, Visayas, and Mindanao.

Following is a list of the regions in their island groupings. To get overviews of the regions, see the respective articles on the island groups. The regions CALABARZON, MIMAROPA, and SOCCSKSARGEN are capitalized because they are acronyms that stand for their component provinces or cities.[20]

  • Component local government units: the data column is limited to primary LGUs, which pertains to component provinces, highly urbanized cities and independent component cities, as well as the independent municipality of Pateros. All city names, except those under the National Capital Region, are italicized.
  • Location: the location map column can be sorted from North-to-South, West-to-East.

Judicial regions[edit]

Note that insofar as the Judiciary is concerned, specifically the first and second level courts, the country is divided into judicial regions as provided by Batas Pambansa Bilang 129. The coverage of these judicial regions generally coincides with that of the administrative regions in the Executive branch of government.

For a list of these judicial regions, see Regional Trial Court#List.

Proposed regions[edit]

  • Bangsamoro (proposed as a replacement of the ARMM. Includes areas outside the current ARMM.)
  • Cordillera Autonomous Region[26] (proposed to convert the Cordillera Administrative Region into an autonomous region.)

Defunct regions[edit]

The following are regions that no longer exist, listed along with their current status:
