Orang Ulu (remote people) is an ethnic designation politically coined to group together roughly 27 very small but ethnically diverse tribal groups in Sarawak, with a population ranging from less than 300 persons to over 25,000 persons. Orang Ulu is not a legal term and no such racial group exist or listed in the Malaysian Constitution. The term was popularised by a minority association known as Orang Ulu National Association (OUNA) that was formed in 1969.
