The Sama-Bajau refers to several Austronesian ethnic groups of Maritime Southeast Asia with their origins from the southern Philippines. The name collectively refers to related people who usually call themselves the Sama or Samah; or are known by the exonyms Bajau (/ˈbɑːdʒaʊ, ˈbæ-/, also spelled Badjao, Bajaw, Badjau, Badjaw, Bajo or Bayao) and Samal or Siyamal (the latter being considered offensive). They usually live a seaborne lifestyle, and use small wooden sailing vessels such as the perahu (layag in Meranau), djenging, balutu, lepa, pilang, and vinta (or lepa-lepa). Some Sama-Bajau groups native to Sabah are also known for their traditional horse culture.
