Tracy Anne Stockwell (born January 11, 1963), née Tracy Anne Caulkins, is an American former competition swimmer, three-time Olympic gold medalist, five-time world champion, and former world record-holder in three events.
Caulkins was noted for her versatility and ability in all four major competitive swimming strokes: the butterfly, breaststroke, backstroke and freestyle. Caulkins won forty-eight national championships and set American records in all four strokes over a range of distances as well as in the individual medley events, which combine all four strokes over the course of a single race. Her versatility brought Caulkins many titles and awards, and as a result she is considered one of the greatest swimmers of all time. By the time she retired from competitive swimming in 1984, Caulkins had set five world records and sixty-three American records (more than any other American swimmer, male or female).
