Aside from the Hiligaynons, who settled in Sultan Kudarat around the 17th to 18th centuries along with the Karay-as, other ethnic groups in the province include the Maguindanaons (who constitute the majority of the provincial Muslim population), as well as the Manobos, Tedurays and Blaans, the three autochthonous ethnic groups of the province. Ilocanos and Cebuanos meanwhile are relative newcomers to the province, with the former comprising the majority of the population in the towns of Lambayong and President Quirino, and the latter in the town of Kalamansig.
