Negros Island Region in the context of Negros Oriental

In the Philippines, provinces (Filipino: lalawigan or probinsiya) are one of its primary political and administrative divisions. There are 82 provinces at present, which are further subdivided into component cities and municipalities. The local government units in the National Capital Region, as well as independent cities, are independent of any provincial government. Each province is governed by an elected legislature called the Sangguniang Panlalawigan and an elected governor.

The provinces are grouped into 18 regions based on geographical, cultural, and ethnological characteristics. Thirteen of these regions are numerically designated from north to south, while the National Capital Region, the Cordillera Administrative Region, the Southwestern Tagalog Region (Mimaropa), the Negros Island Region, and the Bangsamoro Autonomous Region in Muslim Mindanao are only designated by acronyms.

Siquijor (/ˌsɪkiˈhɔːr/ SIK-ee-HOR, Tagalog: [sɪkɪˈhɔɾ]), officially the Province of Siquijor (Cebuano: Lalawigan sa Siquijor; Tagalog: Lalawigan ng Siquijor), is a Philippine island province (the third smallest in the country, in terms of population and land area) located within the Negros Island Region. Its largest town and capital is the municipality of Siquijor. The province lies south of Cebu, southeast of Negros Oriental, southwest of Bohol, and north of Mindanao.

During the Spanish colonial period of the Philippines, the Spaniards called Siquijor the Isla del Fuego (Island of Fire), due to the glow of fireflies that swarmed the molave trees.
