Jean Victor de Bruijn (25 November 1913 – 12 February 1979) was a Dutch district officer, soldier, explorer, ethnologist and writer. He spent most of his life in the Dutch East Indies, especially in Dutch New Guinea, working as a colonial administrator and an ethnologist. He gained fame for holding out with native Papuan soldiers in mountainous interior of Western New Guinea against overwhelming Japanese forces, as part of Operation Oaktree, maintaining one of the last Dutch-controlled outposts in the Dutch East Indies during World War II.
