RCAF Detachment Gananoque was a relief landing field for the Royal Air Force's No. 31 Service Flying Training School (SFTS) located at RCAF Station Kingston during the Second World War. The airfield was located north of Gananoque, Ontario, Canada. Gananoque consisted of a triangle-shaped runway pattern, one hangar, and a control tower. Gananoque officially became a British Commonwealth Air Training Plan (BCATP) facility in 1942 when RAF training schools became part of the BCATP. The station opened in 1940 and closed in 1945.

The airfield was constructed in a typical BCATP wartime pattern, with three runways formed in a triangle. In approximately 1942 the aerodrome was listed at 44°24′N 76°15′W / 44.400°N 76.250°W / 44.400; -76.250 with a variation of 12 degrees west and elevation of 395 ft (120 m). Three runways were listed as follows:

Runway Name	Length	Width	Surface
5/23	2,400 ft (730 m)	100 ft (30 m)	Hard surfaced
17/35	2,400 ft (730 m)	100 ft (30 m)	Hard surfaced
12/30	2,400 ft (730 m)	100 ft (30 m)	Hard surfaced

Today, the former station is operated as the Gananoque Airport.
