Kenneth Wootson Duke (born January 29, 1969) is an American professional golfer who plays on the PGA Tour Champions.

As a seventh grader in Arkadelphia, Arkansas, he was diagnosed with scoliosis; it was determined that his spine had a curvature of over 26 percent, and he wore a back brace 23 hours a day.

At Arkansas Children's Hospital in Little Rock, on February 25, 1985, the day of the surgery, Duke's spine was at 72 degrees and worsening.

Once a 16-inch metal rod was attached to his spine, the curve of Duke's back was set at 38 degrees, within the range of normal, and that's where it has stayed ever since.

Duke led the Reddies to four straight Arkansas Intercollegiate Conference titles and was a four-time AIC Golfer of the Year.

On June 23, 2013, in his 187th start and after three runner-up finishes in his career, Duke broke through to win his first event on the PGA Tour at the Travelers Championship.

In the playoff, after both players made par on the first extra hole, Duke played his approach to within three feet.
