John McLaughlin (born 4 January 1942), also known as Mahavishnu, is an English guitarist, bandleader, and composer. A pioneer of jazz fusion, his music combines elements of jazz with rock, world music, Western classical music, flamenco, and blues. After contributing to several key British groups of the early 1960s, McLaughlin made Extrapolation, his first album as a bandleader, in 1969. He then moved to the U.S., where he played with drummer Tony Williams's group Lifetime and then with Miles Davis on his electric jazz fusion albums In a Silent Way, Bitches Brew, Jack Johnson, Live-Evil, and On the Corner. His 1970s electric band, the Mahavishnu Orchestra, performed a technically virtuosic and complex style of music that fused electric jazz and rock with Indian influences.

McLaughlin's solo on "Miles Beyond" from his album Live at Ronnie Scott's won the 2018 Grammy Award for the Best Improvised Jazz Solo. He has been awarded multiple "Guitarist of the Year" and "Best Jazz Guitarist" awards from magazines such as DownBeat and Guitar Player based on reader polls. In 2003, he was ranked 49th in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time". In 2009, DownBeat included McLaughlin in its unranked list of "75 Great Guitarists", in the "Modern Jazz Maestros" category. In 2012, Guitar World magazine ranked him 63rd on its top 100 list. In 2010, Jeff Beck called McLaughlin "the best guitarist alive", and Pat Metheny has also described him as the world's greatest guitarist. In 2017, McLaughlin was awarded an honorary doctorate of music from Berklee College of Music.
