Borneo Has No Single Flag—It's an Island Shared by Three Nations
Borneo—the world's third-largest island—has no flag of its own. It's politically divided among three sovereign countries, each with its own national flag flying over their respective territory.
The Three Nations of Borneo

🇧🇳 Yellow, white, black diagonal stripes + crest |
Why No Borneo Flag?
- No Unified Administration: Never a single polity covering the whole island.
- Colonial Legacy: Dutch (south) vs. British (north) spheres → independent Indonesia (1949) & Malaysia (1963).
- Brunei declined joining Malaysia (1963); remained British protectorate until 1984.
- Transboundary Cooperation: Heart of Borneo Initiative (2007) – conservation pact (Indonesia, Malaysia, Brunei) – has a logo, not a flag.
Subnational Flags (Within Countries)
- Indonesian Provinces: Each Kalimantan province has a flag (e.g., West Kalimantan – yellow/green/red).
- Malaysian States: Sabah (red/white/blue + silhouette), Sarawak (red/yellow/black + star).
- Labuan: Federal territory flag.
Cultural Symbols (Not Flags)
- Dayak Motifs: Shield, hornbill, mandau sword – used in festivals, tattoos.
- Orangutan / Rafflesia / Pitcher Plant: Ecological icons.
- Traditional Longhouse: Architectural symbol of communal life.
Borneo is a geographic entity, not a political one. Its "flag" is the canopy of the oldest rainforest on Earth—shared, contested, and irreplaceable.
