Kenneth J. Green (born July 23, 1958) is an American professional golfer who has played on the PGA Tour and the Nationwide Tour.

Green was born in Danbury, Connecticut. He started playing golf at age 12 in Honduras, where his father was principal of the American school and his only choices were golf or soccer. He quit school at 16 to pursue his dream of becoming a professional tour player. He turned pro in 1979 and joined the PGA Tour in 1980.

Green had 5 wins on the PGA Tour; all his wins came in the mid to late 1980s. His first win came in 1985 at the Buick Open, and his last was at the Kmart Greater Greensboro Open in 1989. His best year in professional golf was 1988, when he won two events on the PGA Tour and the Dunlop Phoenix in Japan. His best finish in a major was a T-7 at the 1996 U.S. Open. He played on the 1989 Ryder Cup Team.

During his time in professional golf, Green has had a reputation for rebelliousness and a propensity to pull stunts. He has had over two dozen fines levied by the PGA of America for his bad boy antics. Some of them include sneaking some buddies into The Masters in the trunk of his car, drinking beer on the course while playing with Arnold Palmer at the 1997 Masters, and hitting golf balls through narrow openings in sliding-glass doors. Other fines were for more mundane offenses like swearing on the course, criticizing officials and signing autographs while playing. His personal problems - divorces, gambling, depression - have led to near-financial ruin and have affected his playing time and the quality of his play. In his 40s, Green had difficulty maintaining his PGA Tour playing privileges and was forced to play some on the Nationwide Tour. In 2003, Green achieved a bit of notoriety for jumping into a canal in Palm Beach County, Florida to save his dog, Nip, from the jaws of an alligator.

Green lives in West Palm Beach, Florida. He has two sons, Ken Jr. and Hunter. He is an avid bowler who once rolled a 300 game.
