The Lumad are a group of Austronesian indigenous peoples in the southern Philippines. It is a Cebuano term meaning "native" or "indigenous". The term is short for Katawhang Lumad, the autonym officially adopted by the delegates of the Lumad Mindanao Peoples Federation (LMPF) founding assembly on 26 June 1986 at the Guadalupe Formation Center, Balindog, Kidapawan, Cotabato, Philippines. Usage of the term was accepted in Philippine jurisprudence when President Corazon Aquino signed into law Republic Act 6734, where the word was used in Art. XIII sec. 8(2) to distinguish Lumad ethnic communities from the islands of Mindanao.

The Subanon is an indigenous group to the Zamboanga peninsula area, particularly living in the mountainous areas of Zamboanga del Sur and Misamis Occidental, Mindanao Island, Philippines. The Subanon people speak Subanon languages. The name is derived from the word soba or suba, a word common in Sulu, Visayas, and Mindanao, which means "river", and the suffix -nun or -non, which indicates a locality or place of origin. Accordingly, the name Subanon means "a person or people of the river". These people originally lived in the low-lying areas. However, due to disturbances and competitions from other settlers like the Moros, and migrations of Cebuano speakers and individuals from Luzon and other parts of Visayas to the coastal areas attracted by the inviting land tenure laws, further pushed the Subanon into the interior.
