The Mildenhall Treasure is a large hoard of 34 masterpieces of Roman silver tableware from the fourth century AD, and by far the most valuable Roman objects artistically and by weight of bullion in Britain. It was found at West Row, near Mildenhall, Suffolk, in 1942. It consists of over thirty items and includes the Great Dish which weighs over 8 kg (18 lb).

A hoard or "wealth deposit" is an archaeological term for a collection of valuable objects or artifacts, sometimes purposely buried in the ground, in which case it is sometimes also known as a cache. This would usually be with the intention of later recovery by the hoarder; hoarders sometimes died or were unable to return for other reasons before retrieving the hoard, and these surviving hoards might then be uncovered much later by metal detector hobbyists, members of the public, and archaeologists.
