Royal Air Force Great Ashfield or more simply RAF Great Ashfield is a former Royal Air Force station located 10 miles (16 km) east of Bury St. Edmunds and 2 miles (3.2 km) south of Great Ashfield, Suffolk, England. Great Ashfield Airfield is still in private use although much reduced in size. It was originally a Royal Flying Corps grass landing strip on this site in World War I, and before the USAAF arrived the RAF had been using it for training, during that period it was known as RAF Elmswell.
