The Mildenhall Treasure is a non-fiction work written by British author Roald Dahl. It tells the story of the discovery in 1942 near Mildenhall in Suffolk of the Mildenhall Treasure, now held in the British Museum.

Mildenhall is a market town and civil parish in the West Suffolk district, in the county of Suffolk, England. The town is near the A11 road, and is 37 mi (60 km) north-west of Ipswich, the county town. The large Royal Air Force station, RAF Mildenhall, as well as RAF Lakenheath, are located north of the town. Both are used by the United States Air Force as the headquarters of its 100th Air Refueling Wing and 352nd Special Operations Group. Mildenhall is often seen as the start of The Fens on the south/east.
