In the Philippines, regions (Filipino: rehiyon; ISO 3166-2:PH) are administrative divisions that primarily serve to coordinate planning and organize national government services across multiple local government units (LGUs). Most national government offices provide services through their regional branches instead of having direct provincial or city offices. Regional offices are usually but not necessarily located in the city designated as the regional center.

As of 2024, the Philippines is divided into 18 regions. Sixteen of these are mere administrative groupings, each provided by the president of the Philippines with a regional development council (RDC) – in the case of the National Capital Region (Metro Manila), an additional metropolitan authority serves as the coordinating and policy-making body. Only one, the Bangsamoro Autonomous Region in Muslim Mindanao, has an elected government and parliament to which the Congress of the Philippines has delegated certain powers and responsibilities.

## History[edit]

Regions first came to existence on September 24, 1972, when the provinces of the Philippines were organized into eleven regions under Presidential Decree No. 1 as part of the Integrated Reorganization Plan of President Ferdinand Marcos.[1] Since that time, other regions have been created and some provinces have been transferred from one region to another.

### Timeline[edit]

* June 22, 1973 – Pangasinan is transferred from Central Luzon (Region III) to the Ilocos Region (Region I).[2]
* July 7, 1975 – Region XII is created, and some regions of Mindanao are reorganized.[3]
* July 25, 1975 – Regions IX and XII are declared as Autonomous Regions in Western and Central Mindanao, respectively.[4]
* August 21, 1975 – Region IX is divided into Sub-Region IX-A and Sub-Region IX-B. Some regions in Mindanao are reorganized.[5]
* November 7, 1975 – Metro Manila is created.[6]
* January 23, 1976 – Metro Manila is separated from Southern Tagalog to become Region IV; Southern Tagalog becomes Region IV-A.[7]
* June 2, 1978 – Metro Manila is declared the National Capital Region.[8]
* June 11, 1978 – The regional center of Region IX is transferred from Jolo, Sulu, to Zamboanga City.[9]
* July 15, 1987 – The Cordillera Administrative Region is created.[10]
* August 1, 1989 – The Autonomous Region in Muslim Mindanao (ARMM) is created.[11] Region XII reverted to an administrative region.
* January 30, 1990 – Residents reject in a plebiscite the ratification to create the Cordillera Autonomous Region.[12]
* October 12, 1990 – Executive Order No. 429 is issued by President Corazon Aquino to reorganize the Mindanao regions, but the reorganization never happened (possibly due to lack of government funds).[13]
* February 23, 1995 – Region XIII (Caraga) is created and minor reorganization of some Mindanao regions; Sultan Kudarat is transferred to Region XII.[14]
* 1997 – Minor reorganization of some Mindanao regions.

* July 17, 2016 – Republic Act No. 10879 establishes the Southwestern Tagalog Region (Mimaropa Region) from the former Region IV-B (in effect merely a renaming and discontinuation of the "Region IV-B" designation since no boundary changes were involved).[23]
* August 9, 2017 – Executive Order No. 38 is signed by President Rodrigo Duterte, abolishing the Negros Island Region.[24]
* January 25, 2019 – The Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) is created, replacing the Autonomous Region in Muslim Mindanao (ARMM) after Republic Act No. 11054 or the Bangsamoro Organic Law is "deemed ratified" on January 25, 2019, following the January 21 plebiscite.[25][26][27]
* June 13 2024 - President Ferdinand Marcos Jr. signs the Negros Island Region Act, Bringing Negros Occidental, Negros Oriental, and Siquijor into one region.[28]

## List of regions[edit]

As of June 13, 2024[update], the Philippines is divided into 18 regions.[29] The traditional island groups of Luzon, the Visayas, and Mindanao are composed of eight (Regions I, II, III, IV-A, and V, and CAR, NCR, and Mimaropa), four (VI, VII, VIII, and NIR), and six (IX, X, XI, XII, XIII, and BARMM) regions, respectively. The names of Calabarzon, Mimaropa, and Soccsksargen are acronyms signifying their component provinces and cities; and are usually capitalized in official government documents.

### Types of regions[edit]

#### Administrative region[edit]

An administrative region is a grouping of geographically adjacent LGUs that may be established, disestablished, and modified by the president of the Philippines based on the need to formulate coherent economic development policies, more efficiently provide national government services, and coordinate activities beneficial to the development of larger area beyond the province level. No plebiscites have been conducted so far to democratically confirm the creation, abolition or alteration of the boundaries of regular administrative regions, as the Constitution does not mandate it.[30]

An administrative region is not a local government unit (LGU), but rather a group of LGUs to which the president[31] has provided an unelected policy-making and coordinating structure, called the Regional Development Council (RDC).[32] Metro Manila is recognized in law as a "special development and administrative region", and was thus given the Metropolitan Manila Development Authority (MMDA);[33] the Metro Manila Council within the MMDA serves as the National Capital Region's RDC.[32]

On June 13 2024, President Bongbong Marcos signs the Negros Island Region Act, bringing Negros Occidental, Negros Oriental, and Siquijor into one region.[28]

#### Autonomous region[edit]

Main article: Autonomous regions of the Philippines

The 1987 Constitution allows for the creation of autonomous regions in the Cordillera Central of Luzon and the Muslim-majority areas of Mindanao.[30] However, only the Bangsamoro Autonomous Region in Muslim Mindanao and its predecessor, the Autonomous Region in Muslim Mindanao, have been approved by voters in plebiscites held in 1989, 2001, and 2019. Voters in the Cordilleras rejected autonomy in 1990 and 1998; hence the Cordillera Administrative Region remains as a regular administrative region with no delegated powers or responsibilities.

The Supreme Court has ruled that an autonomous region established by statute must be composed of more than one province, thereby invalidating the proposed establishment of the Autonomous Region of Ifugao following the results of the original 1990 Cordillera autonomy plebiscite, which saw only Ifugao's voters casting a majority 'yes' vote towards autonomy.[34]

### Table of regions[edit]

1. ^ Land area figures are the sum of each region's component provinces and independent cities, derived from the National Statistical Coordination Board (Philippine Statistics Authority) official website. For the BARMM, land area is derived from the Bangsamoro Development Plan Integrative Report.[36][37][38]
2. ^ a b c d e f g h i j k l m n o p q A highly urbanized city, independent from any province.
3. ^ a b c d e An independent component city, not under the jurisdiction of any provincial government.
4. ^ Formerly designated as Region IV-B until 2016.
5. ^ A component city, part of the province of Basilan, but whose regional services are provided by the offices of Region IX.
6. ^ a b The province of Cotabato, which is part of the Soccsksargen region, has 63 of its barangays included in the BARMM.
7. ^ Following the Bangsamoro autonomy plebiscite and the ratification of the Bangsamoro Organic Law, the Autonomous Region in Muslim Mindanao (ARMM) was superseded by the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) in February 2019, which transferred the provinces and cities already in the ARMM, as well as surrounding communities that voted for inclusion.

### Judicial regions[edit]

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

As far 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 1980, with some exceptions.

### Legislative districts[edit]

Representation for the Interim Batasang Pambansa was mostly through parliamentary districts based on how regions were organized in 1978. Metro Manila was "Region IV", while Southern Tagalog was "Region IV-A". This was the only time the national legislature was represented via regions; in a 1984 plebiscite, voters approved a constitutional amendment that reverted to representation per province and city.

## Proposed regions[edit]

* Cordillera Autonomous Region[40] (proposal to convert the Cordillera Administrative Region into an autonomous region; see Cordillera autonomy movement)
* Samar Administrative Region[41]
* Bangsa Sug[42][43][44] (proposed to separate the Sulu Archipelago from the mainland portion of Bangsamoro)

## Defunct regions[edit]

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

* Southern Tagalog (Region IV, now divided into Calabarzon, Central Luzon (Aurora), Metro Manila (several cities that were part of Rizal), and Mimaropa; the name remains as a cultural-geographic region only)
* Western Mindanao (renamed as Zamboanga Peninsula, still designated as Region IX)
* Central Mindanao (now mostly Soccsksargen, still designated as Region XII)
* Southern Mindanao (now mostly Davao Region, still designated as Region XI)
* Autonomous Region in Muslim Mindanao (replaced by Bangsamoro)
