Great Waldingfield is a village and civil parish in the Babergh district of Suffolk, England about two miles (3 km) north-east of Sudbury and two miles (3 km) south-west of its sister village, Little Waldingfield.

Located on the major thoroughfare between the wool town of Lavenham and Sudbury, the village was well-placed to benefit from the trade boom in the late Middle Ages.

In 1648, during the siege of Colchester (part of the English Civil War) Cromwell's Ironsides were billeted in the village, an area which became Garrison Lane.

The late 19th and early 20th centuries saw a steady decline in population, caused by out-migration and a flu epidemic, from 659 in 1851 to 348 in 1931.

For security reasons named Station 174 by the United States Army Air Force, the airfield was later more commonly known as RAF Sudbury.
