Cuyunon refers to an ethnic group populating Cuyo, northern and central Palawan. The Cuyunons are originally from Cuyo, and the surrounding Cuyo Islands, a group of islands and islets in Sulu Sea, to the north eastern of Palawan. They are considered an elite class among the hierarchy of native Palaweños. Currently, there are ten Punong Datus ( chief datus ) of the Cuyonon Tribe. The Ten Members of the Council of Datus of the Cuyonon Tribe are:
Datu Higinio Clark Mendoza, II, Datu Freddie Ponce de Leon, II, Datu Ferdinand Blanco, Datu Andrei Ustares Acosta, Datu Prospero Castro, Datu Wilfredo Magdayao, Datu Jim Pe, Datu Felipe Acosta, II, Datu Rogelio Alili, and Datu Robert Rover.
During the Spanish colonization of the Philippines, Cuyo was one of the territories of Palawan that had a strong Spanish presence.
The first Miss Philippines was a Cuyunon. And, when Vietnam, opened its doors to the world, the first ambassador from the Philippines was also a Cuyunon. It was also a Cuyunon who topped the Philippines' very first Civil Service Examination- Mr. Procopio Macolor, Sr.
