Fort Yawuh is a jazz album by American pianist and composer Keith Jarrett. Originally released in 1973 by Impulse! Records, it marks the beginning of the label’s relationship with Jarrett. Recorded live at the Village Vanguard on February 24, 1973 by Jarrett's "American Quartet": Dewey Redman on tenor saxophone, Charlie Haden on acoustic bass, Paul Motian on drums, plus percussionist Danny Johnson. The title of the album is an anagram of "Fourth Way," a reference to George Gurdjieff's fourth path of self-awareness.
