Ottawa / Rockcliffe Airport (CYRO) is a small general aviation airport located in the east end of Ottawa, Ontario, Canada, situated along the Ottawa River. It serves private pilots, flight training operations, and recreational aviation rather than scheduled commercial airline service. The airport is home to the Canada Aviation and Space Museum, one of the country's premier aviation heritage institutions, making it a notable destination for aviation enthusiasts. The museum's collection and the airport's historic character reflect Rockcliffe's long association with Canadian aviation history. Rockcliffe has no scheduled passenger airline service and does not function as a commercial terminal airport. It primarily supports general aviation activity in the National Capital Region, complementing the larger Ottawa Macdonald–Cartier International Airport which handles commercial traffic.
