Bangui, officially the Municipality of Bangui (Ilocano: Ili ti Bangui; Filipino: Bayan ng Bangui), is a municipality in the province of Ilocos Norte, Philippines. According to the 2020 census, it has a population of 15,019 people.

The first power generating windmill farm in Southeast Asia, commonly known as Bangui Wind Farm, is found in the municipality of Bangui.

Bangui was first founded in 1786, and was formally given its current status as a municipality in 1913.

Bangui was one of the Ilocos region municipalities where various human rights violations were documented during the martial law era, despite public perception that the region was supportive of the Marcos administration. Eight farmers in Bangui are documented to have been "salvaged" in 1984, the same year as three indigenous community members in Vintar, while farmers from the towns of Vintar, Dumalneg, Solsona, Marcos and Piddig were also documented to have been tortured.

The Bangui Wind Farm project of NorthWind Power Development Corp. (NorthWind) began commercial operation in 2005, eventually becoming a major tourist site for Bangui. Ayala-owned AC Energy eventually took control of Northwind and of the Bangui Wind Farm in 2017, acquiring a total of 67.79% of Northwind stocks.

Bangui is 554 kilometres (344 mi) from Metro Manila and 67 kilometres (42 mi) from Laoag City, the provincial capital.

Bangui is politically subdivided into 14 barangays.  Each barangay consists of puroks and some have sitios.

On August 10, 2012, Barangay San Isidro was transferred to Dumalneg town based on the decision of Supreme Court over the disputed barangay.

Bangui is well known because of its wind farm, which is the town's main attraction. Although the Burgos and Caparispisan (Pagudpud) Windmills were built in 2013, many visitors still visit Bangui Windmills.

Bangui Bay is also a tourist spot, yet not practical for swimming because of its deepness and water currents, but it is beautiful to view. There is also Abang Falls that can be found in Barangay Lanao, also a tourist spot. Bangui is also good for its beautiful view of mountains and rivers.

Another important tourist attraction is the 400-year old St. Lawrence the Deacon Parish Church, located just adjacent to the Municipal Plaza. The Parish Church is currently under the parochial administration and management of the Congregation of the Rogationists of the Heart of Jesus (Rogationist Fathers), within the canonical jurisdiction of the Roman Catholic Diocese of Laoag. It still features the remains of the old church and the convent, whose institution was initiated by the Augustinians (Order of Saint Augustine - OSA).
