James Oscar Smith (December 8, 1928 – February 8, 2005 Norristown, PA) was an American jazz musician who helped popularize the Hammond B-3 organ, creating a link between jazz and 1960s soul music.

In 2005, Smith was awarded the NEA Jazz Masters Award from the National Endowment for the Arts, the highest honor that America bestows upon jazz musicians. He purchased his first Hammond organ, rented a warehouse to practice in and emerged after little more than a year. Upon hearing him playing in a Philadelphia club, Blue Note‘s Alfred Lion immediately signed him to the label and his second album, The Champ, quickly established Smith as a new star on the jazz scene. He was a prolific recording artist and, as a leader, dubbed The Incredible Jimmy Smith, he recorded around forty sessions for Blue Note in just eight years beginning in 1956. Albums from this period include The Sermon!, House Party, Home Cooking’, Midnight Special, Back at the Chicken Shack and Prayer Meetin’.
