The D-Day Story (formerly the D-Day Museum) is a visitor attraction located in Southsea, Portsmouth in Hampshire, England. It tells the story of Operation Overlord during the Normandy D-Day landings. Originally opened as the D-Day Museum in 1984 by Queen Elizabeth The Queen Mother, it reopened as the D-Day Story, following a refurbishment funded by a £5 million Heritage Lottery grant, in March 2018. The museum building was designed by the then city architect .
