RAF Sedgeford was a Royal Air Force airfield, located approximately 15 miles north-northeast of King's Lynn, in the county of Norfolk, East Anglia.

RAF Sedgeford was used as an airfield in the First World War, as a satellite airfield (officially called "Night Landing Grounds") of RAF Great Yarmouth.

[1] During the First World War, the airfield was used for home defence duties, and was initially attached to the Royal Navy.

[2] RAF Sedgeford was reused during the Second World War, when it was classified as a 'Q-type' and 'K-type' bombing decoy.

Smaller buildings, dating back to the First World War, survive, as does an air raid shelter that was built during the Second World War.
