Kabacan is a first class municipality in the province of Cotabato, Philippines. According to the 2015 census, it has a population of 89,161 people.

The town is predominantly composed of rice farms made possible by the influx of Ilocano-speaking people from northern Philippines. The University of Southern Mindanao is in Kabacan. It is strategically located between the cities of Cotabato and Davao from west to east and the cities of Cagayan de Oro from the north and General Santos from the south.

Kabacan got its name from the word “ka-abacan” which means the source of abundance. People from far-flung barangays used to come to this place and, upon returning home, they brought with them many commodities of their livelihood.

The municipality of Kabacan was a barrio of the municipal district of Pikit before its creation as a district political body. It was created as a regular municipality by virtue of Executive Order No. 82 dated August 18, 1947, issued by President Manuel Roxas of the Republic of the Philippines.

Growth was gradual under the domain of Datu Mantawil; that influx of settlers from Luzon and Visayas arrived in the 1930s. This was made so when the McLareen family sold its hacienda to Jose Yulo Alano, Rafael Alunan and party who organize a company under the cooperate name of Rio Grande Estate. The company be came the people's place of business and social center. Recognizing his immense power and leadership over the area, the provincial governor of Cotabato organizes the Kabacan into a Municipal District with Datu Mantawil as its first mayor in 1935.

When the Second World War broke out and the Japanese Imperial Army occupied the country, the Rio Grande Rubber Estate was sold by the Filipino Incorporators to the Japanese Imperial Government. It became the site for the provisional municipal government with Cenon Doctolero as the appointed mayor. The Japanese garrison was attacked Oct. 25, 1942, by guerrilla forces under U.S. Lieut. Col. Wendell Fertig. During a fourteen-day siege sixty-eight of the seventy-six Japanese garrison were killed. Only the arrival of reinforcements saved the garrison and caused the guerrillas to withdraw.
