Singkawang Airport (ICAO: WIOI) is a small general aviation airfield located near the city of Singkawang in West Kalimantan province, on the island of Borneo, Indonesia. The airport serves the Singkawang area, which is one of the larger cities in West Kalimantan after the provincial capital Pontianak. The airport has historically had limited or no scheduled commercial passenger services, functioning primarily for general aviation and occasional charter operations. The region's air travel needs are largely served by Abdul Rachman Saleh or Supadio International Airport in Pontianak, which lies to the south. Singkawang is known for its significant ethnic Chinese population and cultural heritage, and the city has seen development interest over the years, though its airport remains a minor facility with limited infrastructure.
