The Tiruray or Teduray are another distinct ethno-linguistic group with clear proto-Malayan features. They are mostly found in Maguindanao and Sultan Kudarat Provinces. The Tiruray have a solid social structure as reflected by their socio-economic activities, which include farming, hunting, fishing and basket weaving. While many have adapted to the political mainstream, a high number of their population still believe and practice their indigenous custom and ritual.
Despite the much acculturation, the Tiruray maintain a traditional culture of their own, characterized by communal households, polygamy, and an indigenous moral-legal system. They are known for their craftsmanship in basket weaving in two-toned geometric designs.
The Lambangian are said to be a sub-group belonging to the Tiruray community.
