Ascension is a jazz album by John Coltrane recorded in June 1965 and released in 1966. It is considered a watershed in Coltrane's work, with the albums recorded before it being more conventional in structure and the albums recorded after it being looser, free jazz inspired works. In addition, it signaled Coltrane's interest in moving away from the quartet format. AllMusic called it "the single recording that placed John Coltrane firmly into the avant-garde".

John William Coltrane was an African-American jazz saxophonist, bandleader and composer. He is among the most influential and acclaimed figures in the history of jazz and 20th-century music.
