Fersfield is a village and former civil parish, now in the parish of Bressingham, in the South Norfolk district, in the county of Norfolk, England. The village is located 3.8 miles (6.1 km) north-west of Diss and 19 miles (31 km) south-west of Norwich. It was the home parish of Francis Blomefield, whose History of Norfolk documents the history of much of South Norfolk. In 1931 the parish had a population of 194. On 1 April 1935 the parish was abolished and merged with Bressingham.

Fersfield's name is of Anglo-Saxon origin and derives from the Old English for an area of open land where heifers were kept.

In the Domesday Book, Fersfield is listed as a settlement of 26 households in the hundred of Diss. In 1086, the village was divided between the East Anglian estates of King William I and Robert Malet.

Fersfield falls within the constituency of South Norfolk and is represented at Parliament by Richard Bacon MP of the Conservative Party. For the purposes of local government, the parish falls within the district of South Norfolk.

Fersfield's church is dedicated to Saint Andrew with the exterior dating from the Fourteenth and Fifteenth Centuries, with the interior largely the product of the Nineteenth Century. The remaining stained-glass takes the form of several roundels, likely from the Continent, depicting Saint Andrew, Saint Gregory and the Eagle of Saint John. The font dates from the Norman Conquest with St. Andrew's also holding memorials to the Norman knight, Robert du Bois and the English antiquarian and historian, Francis Blomefield.

RAF Fersfield was built in 1943 for use by various formations from the Royal Air Force and the United States Army Air Forces on strategic-bombing missions of Continental Europe. Fersfield was the departure site for the mission that led to the death of Lt. Joseph P. Kennedy, Jr., the brother of future U.S. President, John F. Kennedy. After the Second World War, RAF Fersfield was briefly used as a venue for motor racing until it reverted to agricultural use.
