Regions of the Philippines


Regions of the Philippines

This article is part of a series on the
politics and government of
the Philippines

In the provinces (lalawigan) of the country for administrative convenience. Currently, the archipelagic republic of the Philippines is divided into 18 regions. 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.

List of regions

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

As of May 2015, the Philippines consists of 18 administrative regions. 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]

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.
