The full countdown was unveiled by Jo Whiley on a special show on the station earlier today (April 1) with the band's 2002 album coming in ahead of Keane's 2004 record Hopes and Fears and Duran Duran's Rio.
A Rush of Blood to the Head was Coldplay's second album and the follow-up to their debut Parachutes. It included the hit singles 'Clocks' and 'In My Place'. It is one of the biggest selling albums of the 21st century in the UK.
The poll included some of Radio 2's most played albums across the last six decades, featuring artists such as The Beatles, The Pet Shop Boys and U2.
Pink Floyd's The Dark Side of the Moon from 1973 ranked fourth with Dido's 1999 debut No Angel completing the top five. Glastonbury headliners The Rolling Stones finished sixth with their album Sticky Fingers.
Jeff Smith, Head of Music BBC Radio 2 and BBC Radio 6 Music, said: "With albums ranging from Sinatra in the '50s to Emeli Sande in the last year, the range of eras and genres exhibited by the chart is typical of the breadth of Radio 2 and its distinctive music policy.
"Musicians such as Coldplay and Dido have struck a chord with listeners and are in good company in the Top 10 alongside legendary bands like The Rolling Stones and The Beatles, whose appeal remains undiminished after all these years."
