Across the Panay Gulf and Guimaras Strait is Negros Occidental, occupying the northwestern half of the larger island of Negros. Iloilo City, its capital, is geographically located in the province and is grouped under the province by the Philippine Statistics Authority but remains politically independent from the provincial government.
