Kenneth Wootson Duke (born January 29, 1969) is an American professional golfer who plays on the PGA Tour Champions.
After turning professional in 1994, Duke bounced around the world playing mini-tours and on the Asian Tour, South American Tour, and the Canadian Tour. In 1999, he won twice on the Canadian Tour and led their Order of Merit. Duke first played on what was then the Nike Tour in 1995 and qualified for the PGA Tour in 2004.
Duke was one of the last players to retain his Tour card via earnings, an exemption the PGA Tour ended prior to the 2017–18 season. Duke was unable to retain full Tour status after the season and became eligible for PGA Tour Champions in January 2019.
