"A Whiter Shade of Pale" is the debut song by the British rock band Procol Harum, released 12 May 1967. The single reached number one in the UK Singles Chart on 8 June 1967 and stayed there for six weeks. Without much promotion, it reached number 5 on the Bilboard pop chart in the United States. One of the anthems of the 1967 Summer of Love, it is one of fewer than 30 singles to have sold over 10 million copies worldwide.

With its haunting Bach-derived instrumental melody, soulful vocals, and unusual lyrics — by the song's co-authors Gary Brooker, Keith Reid, and Matthew Fisher — "A Whiter Shade of Pale" reached No. 1 in several countries when released in 1967. In the years since, it has become an enduring classic. It was the most played song in the last 75 years in public places in the UK (as of 2009), and the United Kingdom performing rights group Phonographic Performance Limited in 2004 recognised it as the most-played record by British broadcasting of the past 70 years. Also in 2004, Rolling Stone placed "A Whiter Shade of Pale" No. 57 on its list of the 500 Greatest Songs of All Time.

In 1977, the song was named joint winner (along with Queen's "Bohemian Rhapsody") of the Best British Pop Single 1952–1977 at the Brit Awards. In 1998 the song was inducted into the Grammy Hall of Fame. More than 1000 recorded cover versions by other artists are known. The song has been included in many music compilations over the decades and has also been used in the soundtracks of numerous films, including The Big Chill, Purple Haze, Breaking the Waves, The Boat That Rocked and notably in Martin Scorsese's segment of New York Stories. Cover versions of the song have also been featured in many films, for example, by King Curtis in Withnail and I and by Annie Lennox in The Net.
