Bengkayang Airport (ICAO: WIOB) is a small general aviation airstrip located in Bengkayang regency on the Indonesian portion of Borneo Island, in the province of West Kalimantan. It serves as a minor regional facility supporting local connectivity in an area characterized by dense jungle and limited ground transportation options. The airport does not currently hold an IATA code, reflecting its limited role in scheduled commercial aviation. It primarily supports light aircraft, charter flights, and occasional government or humanitarian operations rather than regular passenger airline service.
