Royal Air Force Wellingore or more simply RAF Wellingore is a former Royal Air Force fighter relief landing ground located 1.9 miles (3.1 km) south of Navenby, Lincolnshire and 10 miles (16 km) south of Lincoln, Lincolnshire, England.

The airfield was originally opened in 1917 as a Royal Naval Air Service station called Wellingore Heath.

By the winter of 1939/40, the airfield was fully operational and consisted of two grass runways, a concrete perimeter track and several hangars.

In November 1940, Guy Gibson, who later led Operation Chastise (better known as the Dambusters Raid), was stationed at Wellingore.

The station was used as a prisoner of war camp before being handed back to the local land owner.
