Their first Greatest Hits collection, which includes the hits We Will
Rock You and Bohemian Rhapsody, has extended its lead after being
Britain's highest-selling album for several years.
The Official Charts Company said one in three British families now owned a copy of the 1981 compilation.
"I just want to say thanks to everyone who has supported us through the years, we hope to continue to serve you."
Band mate Roger Taylor added: "Wonderful. Who would have thought it? And all due to the great British public. Thank you. A great honour!"
The Official Charts Company said Queen's album - which also features Another One Bites The Dust, Bicycle Race and Fat Bottomed Girls - regularly sells several thousand copies per week, particularly around Christmas.
The majority of the sales have been on vinyl, CD and cassette - with only 124,000 downloads to date.
"Becoming the first album to pass six million sales is a quite incredible achievement by Queen," said Martin Talbot, chief executive of the Official Charts Company.
"Ever since it was first released in 1981, this package of classic pop and rock tracks has been an indispensable item in every music fan's record collection - perhaps the definitive greatest hits album."
Queen's Greatest Hits is also their biggest-selling album in the US, where it is certified as having sold 8 million copies, according to the Recording Industry Association of America (RIAA).
The band's second hits collection, released a month before lead singer Freddie Mercury's death in November 1991, is the UK's tenth best-selling album, with 3.9 million copies sold to date.

Individually, Queen's albums have plenty of filler (the embarrassing Don't Try Suicide) but the hits album is practically faultless.
They're muscular on We Will Rock You and majestic on Bohemian Rhapsody. But the compilation also shows how weird Queen could be for a mainstream chart act - witness the "we do like to be beside the seaside" coda on Seven Seas of Rhye.
For casual fans, it's the only Queen album they'll need… although getting the second volume wouldn't hurt.
Analysis
They never appear in pundits' polls but many bands' best records are their Greatest Hits: from Abba Gold to Divine Madness. So it's no surprise that one in three households owns a copy of Queen's Greatest Hits.
