John William "Trane" Coltrane (September 23, 1926 – July 17, 1967) was an American jazz saxophonist and composer.

Working in the bebop and hard bop idioms early in his career, Coltrane helped pioneer the use of modes in jazz and later was at the forefront of free jazz. He was prolific, making about fifty recordings as a leader during his recording career, and appeared as a sideman on many other albums, notably with trumpeter Miles Davis and pianist Thelonious Monk. As his career progressed, Coltrane's music took on an increasingly spiritual dimension. His second wife was pianist Alice Coltrane, and their son Ravi Coltrane is also a saxophonist.

He influenced innumerable musicians, and remains one of the most significant tenor saxophonists in jazz history. He received many awards, among them a posthumous Special Citation from the Pulitzer Prize Board in 2007 for his "masterful improvisation, supreme musicianship and iconic centrality to the history of jazz."
