Buug, officially the Municipality of Buug (Cebuano: Lungsod sa Buug; Chavacano: Municipalidad de Buug; Tagalog: Bayan ng 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.

Buug grew into a thriving community through the initiative of the timuays, the Subanen chieftains, who held leadership of the community. A school was opened which drew in the first trickle of Subanon, Cebuano, and other Visayan settlers. When the Samar Mining Company (SAMICO) opened the Sibuguey project in 1957 at Bobuan (now part of the municipality of Bayog), the next group of settlers flooded in. More people came when the Pagadian-Zamboanga National Highway reached Buug in 1958. The highway is part of the Pan-Philippine Highway (also known as the Maharlika Highway and AH26).

Buug was originally a barangay of the municipality of Margosatubig and became a baranggay of Malangas when the former was divided in 1951. It became a municipality through Executive Order No. 380 issued by President Carlos P. Garcia on February 2, 1960. Instrumental in the formation of the Municipality of Buug was the persistence of Mr. Quirino M. Gonzales, a fisherman who also was a councilor of Malangas and a native of Merida, Leyte. He is also a distant relative of then Senator Neptali Gonzales. Gonzales became the first appointed mayor and was called the "Father of Buug". After being proclaimed as a municipality, flocks of settlers established residence and trade in the place.
