Orang Ulu
Orang Ulu ("people of the interior" in Malay) is an ethnic designation politically coined to group together roughly 27 very small but ethnically diverse tribal groups in northeastern Sarawak, Malaysia with populations ranging from less than 300 persons to over 25,000 persons. "Orang Ulu" is not a legal term, and no such racial group exists or is listed in the Malaysian Constitution. The term was popularised by the Orang Ulu National Association (OUNA), which was formed in 1969.
