The Prince Regent (George IV) 'Battle of Waterloo' Souvenir Silver Medal refers to a private or commemorative issue created to mark the Allied victory at Waterloo, distinct from the official Waterloo campaign medal awarded to participants.

While the reigning monarch in 1815 was King George III, the official British Waterloo Medal was issued in the name of the Prince Regent (the future George IV), as George III was incapacitated by mental illness at the time. The official medal features the inscription "GEORGE P. REGENT" on the obverse, not the king's direct name or portrait.

The reverse depicts a seated figure of Victory atop a plinth, with the words 'WELLINGTON', 'WATERLOO', and the date 'JUNE 18 1815', inspired by classical Greek art.
