Pannai, Panai or Pane was a Buddhist kingdom located on the east coast of Northern Sumatra that existed between the 11th and 14th centuries. The kingdom was located on the Barumun River and Panai River valleys, in today's Labuhan Batu and South Tapanuli regencies. Because surviving inscriptions and historical records of this period are scarce, the kingdom is among the least known political entities in Indonesian history. Historians suggest that Pannai was probably a principality or a vassal allied under the Srivijayan mandala and later to Dharmasraya kingdom.
