{{Politics of the Philippines}}
In the [[Philippines]], '''regions''' ({{langx|fil|rehiyon}}; [[ISO 3166-2:PH]]) are [[Administrative divisions of the Philippines|administrative divisions]] that primarily serve to coordinate planning and organize national government services across multiple [[Local government in the Philippines|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. Seventeen 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 [[Metro Manila|National Capital Region]] (Metro Manila), an additional [[Metropolitan Manila Development Authority|metropolitan development authority]] serves as the coordinating and policy-making body. Only one, the [[Bangsamoro|Bangsamoro Autonomous Region in Muslim Mindanao]], has an elected government and [[Bangsamoro Parliament|parliament]] to which the [[Congress of the Philippines]] has delegated certain powers and responsibilities.

== History ==
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]].<ref>{{Cite book |title=Integrated Reorganization Plan: Reorganization of the Executive Branch of the National Government |publisher=Presidential Commission on Reorganization |year=1972 |pages=12–13}}</ref> Since that time, other regions have been created and some provinces have been transferred from one region to another.

=== Types of regions ===
==== Administrative region ====
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.<ref name="artx">{{cite web|url=https://www.officialgazette.gov.ph/constitutions/the-1987-constitution-of-the-republic-of-the-philippines/the-1987-constitution-of-the-republic-of-the-philippines-article-x/|title=The 1987 Constitution of the Philippines – Article X, Local Government|author=Republic of the Philippines|date=1987|access-date=August 9, 2019|website=The Official Gazette of the Republic of the Philippines}}</ref>

==== Autonomous region ====
{{Main|Autonomous regions of the Philippines}}

The 1987 Constitution allows for the creation of [[autonomous administrative division|autonomous regions]] in the [[Cordillera Central (Luzon)|Cordillera Central]] of [[Luzon]] and the [[Moro people|Muslim-majority]] areas of [[Mindanao]].<ref name="artx"/> However, only the [[Bangsamoro|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 Autonomous Region in Muslim Mindanao expansion and inclusion plebiscite|2001]], and [[2019 Bangsamoro autonomy plebiscite|2019]]. Voters in the Cordilleras rejected autonomy in 1990 and [[1998 Cordillera Autonomous Region creation plebiscite|1998]]; hence the [[Cordillera Administrative Region]] remains as a regular administrative region with no delegated powers or responsibilities.
 
The [[Supreme Court of the Philippines|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.<ref>{{cite web|url=http://lawlibrary.chanrobles.com/index.php?option=com_content&view=article&id=31064:g-r-no-93054-december-4,-1990-alexander-p-ordillo,-et-al-v-commission-on-elections,-et-al&catid=1270&Itemid=566|website=ChanRobles Law Library|title=G.R.

=== Judicial regions ===
{{for|a list of these judicial regions|Regional Trial Court#List}}
As far as the [[judiciary]] is concerned, specifically the first and second level courts, the country is divided into [[Administrative divisions of the Philippines#Judicial regions|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 ===
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; [[1984 Philippine constitutional plebiscite|in a 1984 plebiscite]], voters approved a constitutional amendment that reverted to representation per province and city.
