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.
