Cornwall Regional Airport (IATA: YCC, ICAO: CYCC) is located 7 nautical miles (13 km; 8.1 mi) east-northeast of the city of Cornwall, Ontario, Canada, across the St. Lawrence River from Massena, New York, United States. It has a single, 3,510 ft × 100 ft (1,070 m × 30 m) paved runway oriented east–west.

The airport is classified as an airport of entry by Nav Canada and is staffed by the Canada Border Services Agency (CBSA) on a call-out basis from the Three Nations Crossing. CBSA officers at this airport can handle general aviation aircraft only, with no more than 15 passengers.

In November 2012, after negotiations with the airport commission, Canadian manufacturing company Bushcaddy Aircraft Canada moved its production to the airport and also accepted a contract to operate the UNICOM radio service.

In August 2022, it was announced by Mark Gerretsen, Member of Parliament for Kingston and the Islands, that Cornwall Regional Airport will be receiving $1.1-million through the federal government's Regional Air Transportation Initiative (RATI).
