Terje Rypdal (born 23 August 1947 in Oslo) is a Norwegian guitarist and composer. Most of his music has been released on albums of the German record label ECM. Rypdal has collaborated both as a guitarist and as a composer with other ECM artists such as Ketil Bjørnstad and David Darling. Over the years, he has been an important member in the Norwegian jazz community.
Starting out as a Hank Marvin-influenced rock guitarist with The Vanguards, Rypdal turned towards jazz in 1968 and joined Jan Garbarek's group and later George Russell's sextet and orchestra. An important step towards international attention was his participation in the free jazz festival in Baden-Baden, Germany in 1969, where he was part of a band led by Lester Bowie. During his musical studies at Oslo university and conservatory, he led the orchestra of the Norwegian version of the musical ''Hair''. He has often been recorded on the ECM record label, both jazz-oriented material and classical compositions (some of which do not feature Rypdal's guitar).
His compositions "Last Nite" and "Mystery Man" were featured in the Michael Mann film ''Heat'', and included on the soundtrack of the same name.
