John Patton (July 12, 1935 – March 19, 2002) was an American jazz, blues and R&B pianist and organist often known by his nickname, Big John Patton.

Patton was one of the most in-demand organists during the golden era of the Hammond B-3 organs between 1963 and 1970.He recorded extensively for Blue Note and performed or collaborated with Lloyd Price, Grant Green, and Lou Donaldson. Patton had a lower profile in the 1970s but enjoyed a comeback in the 1980s and 1990s, often in collaboration with saxophonist John Zorn. His later music incorporated modal and free jazz.

John Patton, born in Kansas City, Missouri, United States, was an American jazz composer and performer. He developed the nickname “Big John”, not because of his size, but because of a song. “Remember the tune, ‘Big Bad John’? … yeah, well, that’s what they started calling me and at first I didn’t understand it but I love it now. It’s just a name; if it’s going to help you, then boogie on up in there!
