Libungan is a second class municipality in the province of Cotabato, Philippines. According to the 2015 census, it has a population of 48,768 people.

Libungan was known by various names by its early settlers. The Manobo settlers of the area initially called the area as "Dasdas" which means road down by the river. "Libungan" is used to refer to the river located in the area by the Manobo which means cheater. During the earlier period of settling the place, the Libungan River changes its course which adversely affected the crops which led the settlers to believe that the river was "cheating" them. The area from then on was referred to as Libungan. "Tubak" is one of the earlier names used to refer to the place which means "eroding river".

The Manobo are the earlier settlers of the place and was eventually settled by other ethnic groups mainly by Cebuanos from Cebu who found the place suitable for them because of its terrain. Many immigrants from Luzon and Visayas came to settle in Libungan in the early 1930s. During World War II, the area of Demapaco was used by guerrillas as hideouts and the Libungan River became a battleground. After the Liberation in 1945, more settlers came to Libungan who cleared the forest and used the area's fertile lands for agriculture.

In 1955, when Libungan was still a part of Midsayap, many Libungan residents were elected to the Municipal Council of Midsayap. The Midsayap Municipal Council passed a resolution to the Provincial Government which in turn pass a similar resolution to the national government which seeks to create the Municipality of Libungan. Libungan was established as a separate municipality in August 7, 1961. Under Executive Order No. 414 dated January 27, 1961, Libungan was established as a regular municipality with 14 barangays. The number of barangays within Libungan increased to 32 in the following years but in 1969, Alamada, a new municipality was created from some of Libungan's barangays.

After the creation of Alamada, the municipality maintained its 19 barangays, part of which are the former barangays of Midsayap, namely Libungan (Poblacion), Barongis, Cabaruyan, Batiocan, Sinawingan, Baguer, Montay and Demapaco. Other barangays that compose the municipality are Abaga, Cabpangi, Grebona, Gumaga, Kapayawi, Kiloyao, Malengen, Sinapangan, Kitubod, Nicaan and Palakat, which later became defunct. Under Resolution No. 35 dated December 14, 1978, Palao and Ulamian was established with the total number of barangays of Libungan becoming 20.
