Jet Ski Lady (foaled 20 February 1988) was an American-bred, Irish-trained Thoroughbred racehorse, best known for winning the Epsom Oaks in 1991. In a racing career which lasted from June 1990 to October 1991 the filly ran ten times and won four races. After winning twice as a two-year-old, Jet Ski Lady competed against colts with mixed success in early 1991 before winning the Classic Oaks over one and a half miles at Epsom Downs Racecourse.
