The River Kyle is a small river in North Yorkshire, England. At just under 6 miles long, it is one of the shortest classified main rivers in the country.
The river is first called Kyle after the confluence of Carle Beck and Derrings Beck. From the confluence it flows south-east of the village of Tholthorpe, near Easingwold, past Flawith, Alne and Tollerton. At Linton-on-Ouse it turns south and joins the River Ouse just north of Newton-on-Ouse.
The river previously formed the boundary of the Forest of Galtres. During the Second World War, RAF Bomber Command operated an airfield near the start of the River Kyle at RAF Tholthorpe. Both the Royal Air Force and the Royal Canadian Air Force flew from this base until its closure in 1945. The river also passes close to the current airfield at RAF Linton-on-Ouse, which was originally opened in 1937 as part of RAF Bomber Command.
