Sudbury Airport or Greater Sudbury Airport (IATA: YSB, ICAO: CYSB) is an airport in the Canadian city of Greater Sudbury, Ontario and is located 11 nautical miles (20 km; 13 mi) northeast of the downtown area, on Municipal Road 86 between the communities of Garson and Skead. Although in many contexts the airport uses the name Greater Sudbury Airport, its official name, as registered with Transport Canada and printed in all aeronautical publications, is still simply Sudbury Airport.

The airport is classified as an airport of entry by Nav Canada and is serviced by the Canada Border Services Agency (CBSA) on a call-out basis from the North Bay/Jack Garland Airport. CBSA officers at this airport currently can handle general aviation aircraft only, with no more than 15 passengers.

The airport is served primarily by regional carrier lines such as Air Canada Express, Bearskin Airlines, and Porter Airlines. It is also a base of Ornge air ambulance service and the Ontario Ministry of the Environment wildfire service.
