Klaus Voormann (born 29 April 1938, Berlin, Germany) is a Grammy Award-winning artist, noted musician, and record producer.

He designed artwork for many bands including The Beatles, Bee Gees, Wet Wet Wet and Turbonegro. His most notable work as a producer was his work with the band Trio, including their worldwide hit "Da Da Da". As a musician, Voormann is best known for being bassist with Manfred Mann 1966-69, and for performing as a session musician on many recordings, including some by former members of The Beatles.

His association with The Beatles dated back to their time in Hamburg in the early 1960s. He lived in the band's London flat with George Harrison and Ringo Starr after John Lennon and Paul McCartney moved out to live with their respective partners, and designed the cover of their album "Revolver", for which he won a Grammy. Following the band's split, rumours circulated of the formation of a group named The Ladders, consisting of Lennon, Harrison, Starr and Voormann. This failed to materialise, although Voormann did play on albums by all three, and was for a time a member of the Plastic Ono Band. In the 1990s, he designed the artwork for the Beatles "Anthology" albums.

In 2009, he released his debut solo album "A Sideman's Journey", which featured many notable musicians, including the two surviving Beatles, performing as "Voormann and Friends".
