ABBA's Gold: Greatest Hits has become the second biggest-selling album after its sales surpassed The Beatles' Sgt. Pepper's Lonely Hearts Club Band.
The Swedish group's 1992 collection has sold more than 5.1 million copies in the UK, 15,000 more than the famous Liverpudlians' 1967 album.
Queen's 1981 Greatest Hits album remains the UK's biggest-selling album of all time, with 5.9 million sales.
ABBA founder and songwriter Björn Ulvaeus told The Official Charts Company: "It feels unreal - outselling the greatest record of all time!"
Official Charts Company managing director Martin Talbot added: "The British people took Agnetha, Bjorn, Benny and Anni-Frid to their hearts from the night that they won the Eurovision Song Contest…in Brighton, 39 years ago.
"So it is perhaps apt that their huge Gold hits album has reached such heady heights all these years later."
ABBA won the Eurovision Song Contest in 1974 with Waterloo.
