Buug, officially the Municipality of Buug, is a 3rd class municipality in the province of Zamboanga Sibugay, Philippines. According to the 2020 census, it has a population of 38,425 people. The name Buug was derived from the word bog, a Subanen word for secondary forest which is the same as the Cebuano-Visayan term buog. Accordingly, a group of Subanens stumbled upon this bog that was endowed with a stream and sufficient supply of water while they were moving from one place to another in search of a safe place to start a living away from marauders who were in search for slaves and things to loot. From then on people began to refer to the bog as Buug.
