Oshawa Executive Airport (IATA: YOO, ICAO: CYOO) is a municipal airport adjacent to the north end of the city of Oshawa, Ontario, Canada. It is the busiest general aviation airport without scheduled airline service in the Greater Toronto Area by aircraft movements and one of the busiest general aviation only airports in Canada. It includes two paved runways and instrument approaches.

From 2002 to 2008, Oshawa hosted the annual Canadian Aviation Expo, Canada's largest annual aviation event, before the expo moved to John C. Munro Hamilton International Airport in 2009. Oshawa Airport now hosts the Girls Take Flight event that takes place every spring.

The airport is classified as an airport of entry by Nav Canada and is staffed on call by the Canada Border Services Agency. CBSA officers at this airport can handle aircraft with no more than 50 passengers. The officers also provided weekday call out for general aviation arriving from outside Canada to Buttonville Municipal Airport in Markham, Ontario before that airport was closed in 2023.
