David Charles "Dave" Berkoff (born November 30, 1966) is an American former competition swimmer, Olympic champion, and former world record-holder in two events. Berkoff was a backstroke specialist who won a total of four Olympic medals during his career at two different Olympic Games. He is best known for his powerful underwater start, the eponymous "Berkoff Blastoff".

Four years later at the 1992 Summer Olympics in Barcelona, Spain, Berkoff earned another gold medal by swimming for the winning U.S. team in the preliminary heats of the men's 4×100-meter medley relay. He also won a bronze medal by placing third in the 100-meter backstroke.
