The Tboli are one of the indigenous peoples of South Cotabato in Southern Mindanao. From the body of ethnographic and linguistic literature on Mindanao they are variously known as Tboli, T'boli, Tboli, Tiboli, Tibole, Tagabili, Tagabeli, and Tagabulu. They term themselves Tboli or T'boli. Their whereabouts and identity is to some extend confused in the literature; some publications present the Tboli and the Tagabili as distinct peoples; some locate the Tbolis to the vicinity of the Lake Buluan in the Cotabato Basin or in Agusan del Norte. The Tbolis, then, reside on the mountain slopes on either side of the upper Alah Valley and the coastal area of Maitum, Maasim and Kiamba. In former times, the Tbolis also inhabited the upper Alah Valley floor. After World War Two, i.e., since the arrival of settlers originating from other parts of the Philippines, they have been gradually pushed onto the mountain slopes. As of now, they are almost expelled from the fertile valley floor.
