Guimaras locally [ɡimaˈɾas], officially the Province of Guimaras (Hiligaynon: Kapuoran sang Guimaras; Kinaray-a: Kapuoran kang Guimaras; Tagalog: Lalawigan ng Guimaras) is an island province in the Philippines located in the Western Visayas region. Its capital is Jordan. The province is situated in the Panay Gulf, between the islands of Panay and Negros. To the northwest is the province of Iloilo and to the southeast is Negros Occidental. The whole island is part of the Metro Iloilo-Guimaras, one of the twelve metropolitan areas of the Philippines.
The province consists primarily of Guimaras Island, and also includes Inampulugan, Guiwanon (or Guiuanon), Panobolon, Natunga, Nadulao, and many surrounding islets. Geologists have concluded that the island once formed one landmass with Panay.
Guimaras, formerly known as Himal-us, was a sub-province of Iloilo until it was made an independent province on May 22, 1992.
