Western Visayas (Hiligaynon: Kabisay-an Nakatundan; Tagalog: Kanlurang Kabisayaan or Kanlurang Visayas) is an administrative region in the Philippines, numerically designated as Region VI. It consists of six provinces (Aklan, Antique, Capiz, Guimaras, Iloilo and Negros Occidental) and two highly urbanized cities (Bacolod and Iloilo City). The regional center is Iloilo City. The region is dominated by the native speakers of four Visayan languages: Kinaray-a, Hiligaynon, Aklanon and Capiznon. The land area of the region is 20,794.18 km2 (8,028.68 sq mi), and with a population of 7,536,383 inhabitants, it is the most populous region in the Visayas.
On May 29, 2015, the region was realigned, when Western Visayas (Region VI) lost both the province of Negros Occidental and the highly urbanized city of Bacolod to the newly formed Negros Island Region. However, the region was dissolved, resulting in the return of Negros Occidental and Bacolod to Western Visayas Region on August 9, 2017.
The region's current name is in reference to its geographic position in the greater Visayas area.
Regions first came into existence on September 24, 1972, when the provinces of the Philippines were organized into 11 regions by Presidential Decree No. 1 as part of the Integrated Reorganization Plan by President Ferdinand Marcos. The provinces of Aklan, Antique, Capiz, Iloilo (including its then-subprovince of Guimaras), and Negros Occidental were grouped together to form the Western Visayas region.
The province of Palawan was transferred to Region VI (Western Visayas) on May 23, 2005 by Executive Order 429. The Department of the Interior and Local Government announced in June 2005 that the transfer had been completed. However, Palaweños criticized the move, citing a lack of consultation, with most residents in Puerto Princesa City and all municipalities but one preferring to stay with Region IV-B. Consequently, Administrative Order No. 129 was issued on August 19, 2005 to address this backlash. This Order directed the abeyance of Executive Order 429 pending the approval of an implementation plan for the orderly transfer of Palawan from Region IV-B to Region VI. Hence, Palawan is currently still part of Region IV-B.
By virtue of Executive Order No. 183 issued on May 29, 2015, by President Benigno Aquino III, the province of Negros Occidental and its capital, Bacolod, were both removed from Western Visayas in order to form the Negros Island Region along with Negros Oriental. But later regained Negros Occidental and its capital, Bacolod City back into Western Visayas on August 9, 2017 when President Rodrigo Duterte dissolved the Negros Island Region, revoking Executive Order No. 183, s. 2015 through the signage of Executive Order No. 38, citing the reason of the lack of funds to fully establish the NIR according to Benjamin Diokno, the Secretary of Budget and Management.
Western Visayas consists of the major island of Panay and the smaller Guimaras, as well as several outlying islands. It also includes the western half of the larger island of Negros. The region is bordered to the north by the Sibuyan Sea, northeast by the Visayan Sea, east by the province of Negros Oriental in Central Visayas, south by the Iloilo Strait and the Panay Gulf, and west by the Sulu Sea.
