The original name of this place is Calaparan, but when the majority of its inhabitants executed a petition as required by the City Council of Bacolod for the creation of a new Barrio, it was changed to ALANGILAN, which derived from scented flowering trees known as Ilang-Ilang that was grown and existed in the locality. However, on the northeast portion of this barrio there is a body of water continuously flowing known as Alangilan Creek.
