John McLaughlin (born 4 January 1942, Doncaster, West Riding of Yorkshire, England), also known as Mahavishnu John McLaughlin, is an English guitarist, bandleader and composer. His music includes many genres of jazz, and rock, which he coupled with an interest in Indian classical music to become one of the pioneering figures in fusion.

In 2010, guitarist Jeff Beck called him "the best guitarist alive". In 2003, McLaughlin was ranked 49th in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time". Tabla player Zakir Hussain has often referred to him as one of the greatest and most important musicians of our time.
