Dunnville Airport (TC LID: CDU9) was a registered aerodrome located 2 nautical miles (3.7 km; 2.3 mi) south of Dunnville, Ontario, Canada.

It was built during World War II as part of the British Commonwealth Air Training Plan and was home to Royal Canadian Air Force No.6 Service Flying Training School, which opened on 25 November 1940 and closed on 1 December 1944.

On 30 May 2013, all flight operations ceased at the airport to make way for industrial wind turbines.

Located within the village of Port Maitland, it sits on over 400 acres (160 ha) of land.

The popular television show Canada's Worst Driver was filmed on the airport grounds from its sixth season onwards.
