RAF Metheringham was a Royal Air Force station situated between the villages of Metheringham and Martin and 12.1 mi south east of the county town Lincoln, Lincolnshire, England. Operated as a bomber airfield during World War II the station opened in October 1943 and was decommissioned in the spring of 1946.

Although the airfield building programme was far from complete, the station was soon home to No. 106 Squadron Despite having only a single week to settle in, the Squadron was still operational in time for the opening of the Battle of Berlin, and RAF Metheringham's aircrews went to war on 18 November 1943. 106 Squadron and 110 Squadron were the initial residents at Metheringham both arriving during November 1943, although No. 110 Squadron remained at Metheringham only a few weeks before relocating to RAF Waddington and before they flew any operational missions. In 1945 when hostilities ceased No. 106 Squadron had lost 65 Lancaster bombers and 995 aircrew in operations flown from the airfield and other bases.

After VE-Day the Australian No. 467 Squadron RAAF arrived to train with 106 Sqn for planned Tiger Force operations against Japan in the Far East. The end of the war overtook this plan and 467 Sqn disbanded at the start of October 1945. No. 189 Squadron briefly took its place, but this squadron was also soon stood down. No. 106 Squadron remained in service until February 1946 when it too was disbanded. RAF Metheringham was closed to flying and decommissioned shortly thereafter.
