The swimming competitions of the 1984 Summer Olympics were held at the McDonald's Olympic Swim Stadium, located on the University of Southern California (USC) campus.

In addition, the 200-metre individual medley for both men and women returned to the program from a twelve-year absence, following a proposal by the United States Olympic & Paralympic Committee (USOPC).
