Siayan, officially the Municipality of Siayan (Cebuano: Lungsod sa Siayan; Subanen: Benwa Siayan; Chavacano: Municipalidad de Siayan; Tagalog: Bayan ng Siayan), is a municipality in the province of Zamboanga del Norte, Philippines. According to the 2024 census, it has a population of 40,937 people.[5]

On October 1, 1964, President Diosdado Macapagal signed Executive Order No. 114, creating the municipality of Siayan by separating part of Sindangan.[6][7] It was among those executive orders issued to create 33 municipalities, even their respective legislative bills did not pass Congress. However, vice-president Emmanuel Pelaez filed a special civil action for a writ of prohibition to void such issuances, which was unanimously granted by the Supreme Court in 1965 (Pelaez v. auditor general).[8]

On June 17, 1967, Republic Act No. 4989 was enacted without executive approval,[9][10] eventually recreating the municipality by separating 16 barrios, as originally proposed,[6] from its mother entity.[9]

In 1971, the seat of government was transferred from originally-designated Paranglumba to Siayan Proper.[11] Barrio Siayan was created in 1959.[12]
