Lubu people are an ethnic group who live in central Sumatra, Indonesia. They are similar to the Kubu people, and are also ancestral to the Siladang people.[2] They live in the mountainous regions of Padang Lawas, South Tapanuli, and Mandailing Natal regencies (all are located within North Sumatra Province jurisdictions).[3] They are now in the process of being absorbed by the Batak. In the early 20th century, they were a migratory people who lived in tree houses, and now are still a tribal people. Although they live near the rivers, they are fearful of water.[1] They speak the Lubu language.[4]
