Kalgoorlie–Boulder Airport (IATA: KGI, ICAO: YPKG) is an airport in Kalgoorlie, Western Australia. The airport is 3 nautical miles (5.6 km; 3.5 mi) south of the city. It handled 299,055 passengers in the 2021–22 financial year.

The airport is a major hub for fly-in fly-out service due to the mining boom in the region. It is also a hub for the Goldfields Air Services, which offers chartering and flight lessons, along with the Royal Flying Doctor Service, which uses Kalgoorlie as a hub due to the lack of medical assistance for people in the region, transporting major injuries from Kalgoorlie to Perth.
